P.S. I said you learn from experience. I learned from that non sequitor. I stopped at a bar for lunch in Spanish Harlem, right across from Mount Sinai Hospital in NYC. Empty bar, great looking women bartender. And this guy comes in and sits right next to me. And saids, "I ought to shoot everybody in this place." Having learned from Frank T., our guy from above, I didn't give him a typical NY dirty look and ignor him. I gave him my full attention, and I said, "You'll probabily have more fun if you go to the movies."
And we started to talk, and he was a nut case from Mount Sinai out on a week end pass, and he wanted to go to Central Park, 2 blocks away, and shoot everybody he could find. And I talked him out of it, using the reasoning it's tough now, next week will be better and you can start having some fun again in life. or words to that effect.
So if ever you hear someone drop a non sequitor, pay attention to them and don't dust them off.
