I find this very beautiful and touching. Upvoted.
I agree with people above: the sentence re: 'vacuums' doesn't read right. OTOH:
I thought you were gonna go somewhere mind-screwy or creepy with both 2605 and the caretaker watching something moving rapidly on the other side of the room, and I really think you should have gone that direction. Normally I would no-vote under the assumption that this would get edited to be better, but seeing as how that doesn't happen in a timely fashion with contest entries, I'm going to downvote it instead.
Mmh, Scantron, isn't this rather drastic? I don't think Zolgamax should change anything except the vacuum thing. What you suggest here would a be a major change in story and tone. He is free to accept or decline, is he not?
