I had one just an hour ago.
As I was walking home at about midnight, I walked past a kid who asked me to pick him up some smokes from the store. no stores were open at the hour that sell smokes in the neighborhood.
I told him this and he went off on a tirade, throwing words like "douchebag" around pretty freely. I attempt to walk home, and he follows me, asking me what I was doing out at midnight, and where I was going, and where I was coming from, and where I worked.
I humored him, as I didn't feel like killing some spazzed out little kid with a vulcan neck pinch, and told him I work at the video store down the street. He goes on to say "Have you seen that movie? It's a VCR movie, that 2012 or some shit? that shits awesome, I watch that shit all the time" and I say "no, I haven't seen it yet" he says "What? You haven't seen it? That's crazy shit"
I then proceed to keep walking and he says "What's your problem man, you seem all pissed off and shit" I just say I need to get home, and then He has another spazz attack and runs across the street.
I was a little freaked out until about 10 minutes ago that I'd hear banging on the door and some crack addled little kid was going to try and break in and I'd have to beat him up.
