ts on the counter to the left； just out of her reach。 Now they were too close； she could grab them。 And there was more…
The maid came in behind me。 〃Maria；〃 I said； 〃did you clean this room？〃
〃No； Mr。 Forman。〃
〃But the room is different；〃 I said。
She looked around； and shrugged。 〃No； Mr。 Forman。 The same。〃
〃No； no；〃 I insisted。 〃It's different。 Look。〃 I pointed to the lampshade； the changing cloth。 〃Different。〃
She shrugged again。 〃Okay； Mr。 Forman。〃 I read confusion in her face。 Either she didn't follow what I was saying； or she thought I was crazy。 And I probably did look a little crazy； a grown man obsessing about a Winnie…the…Pooh lampshade。
I showed her the cube in my hand。 〃Have you seen this before？〃
She shook her head。 〃No。〃
〃It was under the crib。〃
〃I don't know； Mr。 Forman。〃 She inspected it； turning it in her hand。 She shrugged； and gave it back to me。 She acted casual； but her eyes were watchful。 I began to feel unfortable。 〃Okay； Maria；〃 I said。 〃Never mind。〃
She bent over to scoop up the baby。 〃I feed her now。〃
〃Yes； okay。〃
I left the room； feeling odd。
Just for the hell of it； I looked up 〃SSVT〃 on the Net。 I got links to the Sri Siva Vishnu Temple； the Waffen…SS Training School at Konitz； Nazi Regalia for sale； Subsystems Sample Display Technology； South Shore Vocational…Technical School； Optical VariTemp Cryostat Systems； Solid Surfacing Veneer Tiles for home floors； a band called SlingshotVenus； the Swiss Shooting Federation…and it went downhill from there。
I turned away from the puter。
I stared out the window。
Maria had given me a shopping list； the items scrawled in her difficult hand。 I really should get the shopping done before I picked up the kids。 But I didn't move。 There were times when the relentless pace of life at home seemed to defeat me； to leave me feeling washed out and hollow。 At those times I just had to sit for a few hours。
I didn't want to move。 Not right now。
I wondered if Julia was going to call me tonight； and I wondered if she would have a different excuse。 I wondered what I would do if she walked in one of these days； and announced she was in love with someone else。 I wondered what I would do if I still didn't have a job by then。 I wondered when I would get a job again。 I turned the little surge suppressor over in my hand idly； as my mind drifted。
Right outside my window was a large coral tree； with thick leaves and a green trunk。 We had planted it as a much smaller tree not long after we moved into the house。 Of course the tree guys did it； but we were all out there。 Nicole had her plastic shovel and bucket。 Eric was crawling around on the lawn in his diapers。 Julia had charmed the workmen into staying late to finish the job。 After they had all gone I kissed her； and brushed dirt from her nose。 She said； 〃One day it'll cover our whole house。〃
But as it turned out； it didn't。 One of the branches had broken off in a storm； so it grew a little lopsided。 Coral is soft wood； the branches break easily。 It never grew to cover the house。 But my memory was vivid； staring out the window； I saw all of us again； out on the lawn。 But it was just a memory。 And I was very afraid it didn't fit anymore。 After working for years with multi…agent systems； you begin to see life in terms of those programs。
Basically； you can think of a multi…agent environment as something like a chessboard； and the agents like chess pieces。 The agents interact on the board to attain a goal； just the way the chess pieces move to win a game。 The difference is that nobody is moving the agents。 They interact on their own to produce the oute。
If you design the agents to have memory； they can know things about their environment。 They remember where they've been on the board； and what happened there。 They can go back to certain places； with certain expectations。 Eventually； programmers say the agents have beliefs about their environment； and that they are acting on those beliefs。 That's not literally true； of course； but it might as well be true。 It looks that way。
But what's interesting is that over time； some agents develop mistaken beliefs。 Whether from a motivation conflict； or some other reason； they start acting inappropriately。 The environment has changed but they don't seem to know it。 They repeat outmoded patterns。 Their behavior no longer reflects the reality of the chessboard。 It's as if they're stuck in the past。 In evolutionary programs； those agents get killed off。 They have no children。 In other multi…agent programs； they just get bypassed； pushed to the periphery while the main thrust of agents moves on。 Some programs have a 〃grim reaper〃 module that sifts them out from time to time； and pulls them off the board。
But the point is； they're stuck in their own past。 Sometimes they pull themselves together； and get back on track。 Sometimes they don't。
Thoughts like these made me very uneasy。 I shifted in my chair； glanced at the clock。 With a sense of relief； I saw it was time to go pick up the kids。
Eric did his homework in the car while we waited for Nicole to finish her play rehearsal。 She came out in a bad mood； she had thought she was in line for a lead role； but instead the drama teacher had cast her in the chorus。 〃Only two lines！〃 she said； slamming the car door。 〃You want to know what I say？ I say； 'Look； here es John now。' And in the second act； I say； 'That sounds pretty serious。' Two lines！〃 She sat back and closed her eyes。 〃I don't understand what Mr。 Blakey's problem is！〃
〃Maybe he thinks you suck；〃 Eric said。
〃Rat turd！〃 She smacked him on the head。 〃Monkey butt！〃
〃That's enough；〃 I said； as I started the car。 〃Seat belts。〃
〃Little stink…brain dimrod； he doesn't know anything；〃 Nicole said； buckling her belt。
〃I said； that's enough。〃
〃I know that you stink；〃 Eric said。 〃Pee…yew。〃
〃That's enough； Eric。〃
〃Yeah； Eric； listen to your father； and shut up。〃
〃Nicole 。。。〃 I shot her a glance in the rearview mirror。
〃Sor…ry。〃
She looked on the verge of tears。 I said to her； 〃Honey； I'm really sorry you didn't get the part you wanted。 I know you wanted it badly； and it must be very disappointing。〃
〃No。 I don't care。〃
〃Well； I'm sorry。〃
〃Really； Dad； I don't care。 It's in the past。 I'm moving on。〃 And then a moment later； 〃You know who got it？ That little suckup Katie Richards！ Mr。 Blakey is just a dick！〃 And before I could say anything； she burst into tears； sobbing loudly and histrionically。 Eric looked over at me； and rolled his eyes。
I drove home； making a mental note to speak to Nicole about her language after dinner； when she had calmed down。
I was chopping green beans so they would fit in the steamer when Eric came and stood in the kitchen doorway。 〃Hey Dad； where's my MP3？〃
〃I have no idea。〃 I could never get used to the idea that I was supposed to know where every one of their personal possessions was。 Eric's Game Boy； his baseball glove； Nicole's tank tops； her bracelet 。。。
〃Well； I can't find it。〃 Eric remained standing in the doorway； not ing any closer； in case I made him help set the table。
〃Have you looked？〃
〃Everywhere； Dad。〃
〃Uh…huh。 You looked in your room？〃
〃All over。〃
〃Family room？〃
〃Everywhere。〃
〃In the car？ Maybe you left it in the car。〃
〃I didn't； Dad。〃
〃You leave it in your locker at school？〃
〃We don't have lockers； we have cubbies。〃
〃You look in the pockets of your jacket？〃
〃Dad。 e on。 I did all that。 I need it。〃
〃Since you've already looked everywhere； I won't be able to find it either； will I？〃
〃Dad。 Would you please just help me？〃
The pot roast had another half hour to go。 I put down the knife and went into Eric's room。 I looked in all the usual places； the back of his closet where clothes were kicked into a heap （I would have to talk to Maria about that）； under the bed； behind the bed table； in the bottom drawer in the bathroom； and under the piles of stuff on his desk。 Eric was right。 It wasn't in his room。 We headed toward the family room。 I glanced in at the baby's room as I passed by。 And I saw it immediately。 It was on the shelf beside the changing table； right alongside the tubes of baby ointment。 Eric grabbed it。 〃Hey； thanks Dad！〃 And he scampered off。 There was no point in asking why it was in the baby's room。 I went back to the kitchen and resumed chopping my green beans。 Almost immediately：
〃Daa…ad！〃
〃What？〃 I called。
〃It doesn't work！〃
〃Don't shout。〃
He came back to the kitchen； looking sulky。 〃She broke it。〃
〃Who broke it？〃
〃Amanda。 She drooled on it or something； and she broke it。 It's not fair。〃
〃You check the battery？〃
He gave me a pitying look。 〃 'Course； Dad。 I told you； she broke it！ It's not fair！〃
I doubted his MP3 player was broken。 These things were solid…state devices； no moving parts。 And it was too large for the baby to handle。 I dumped the green beans on the steamer tray； and held out my hand。 〃Give it to me。〃
We went into the garage and I got out my toolbox。 Eric watched my every move。 I had a full set of the small tools you need for puters and electronic devices。 I worked quickly。 Four Phillips head screws； and the back cover came off in my hand。 I found mysel
