[Uryoces]

I had a conversation with a 15 year old when I was was a senior in high school [back in the Iron Age]. Why I even had to have the conversation, I'll never know; this kid was dense.

The conversation was basically:
"So what would you do if I were to pound the sausage out of you?" I asked with annoyance.
"I'd call the cops!" was the response. It was the wrong response to give in front of his friends, because he'd just shown weakness.
"Okay, fair enough. But what's keeping me from kicking your ass. Right. Now. At. This. Very. Moment", I said, puncuating the last phrase. Idiot thought about that for a minute, then his eyes widened, and he stared at me. He walked away, and I never had to have the conversation again.
The answer, of course, was nothing.
