If you want to be in the play, don't forget your lines

Ever notice how people communicate, or should I say don't communicate in groups. Fellow came up to me today, who hardly knows me, and said "boy they're always giving you a hard time aren't they?" My reaction is rather slow to blather so, for a split, rather scary second he and I just stood our ground and looked at each another. He's expecting me to respond with some mindless cliche and I'm looking at him like he's totally fucking nuts. I wanted to say "Don't you realize man, I'm not in the play. I didn't study my lines and I don't have a clue what you're talking about!
