Pressing Your "Buttons"

Complete strangers who come in to a conversation you're having and effectively derailing it.

A bit wordy. And something lots of folks hate.

But I walked in to my geosciences department (back in the college days) lounge and was talking about something that happened which delayed me from meeting with folks in there. I walked through the room, relaying the story and had a funny punchline midway through. I sat down and was about to continue (following the joke), when some pudgy fellow who I'd never seen before went "what, that's it? What a stupid fuckin' story."

I tilted my head and looked to the portly fellow and said "now who in the hell might you be?"
"Paul."
"Paul... Hmm... I've never heard of you... Know what that means?"
"What?"
"It means I don't give two flyin' fucks what you think. Shut your god damn mouth."

He went silent and left the room a few minutes later, and the whole time, my buddies where cracking up. Evidently this Paul is a big-time douche (some guy I've heard folks talk about but never saw), and no one ever worked up the courage in order to talk down to him.

People who talk in the movie theater bug me, too. I'm quite outgoing, though, so I will tell the individual(s) to shut their mouths or else I'll do it for 'em.

Jam it back in, in the dark.
