my favorite is when I do a little modding in the morning and then go to work or go out for lunch or something, and I get back on NG and there's like 10 messages from some kid who's upset and wanted an immediate answer like 12 hours ago.
Or if I leave my IM up by mistake, sometimes I get the weirdest IMs, I think I'm signed up for that one IM random person generator thing, sort of like omegle or whatever, but with AIM and you just randomly get this totally weird IM of like "so do you think the DOW is going to fall below 6000 this year?" and apparently the other person gets the same, and it switches up your usernames too, it's weird. I get a few a those a week. Sometimes if I'm not around, I'll find a whole conversation of "WHO THE FUCK ARE YOU WHY ARE YOU TALKING TO ME!!!"
