LOL - I realize that now. That happened to be my first trip to The Big Apple. : ) (Errr...nice story about Houston...yikes!)
I used to work in the University District in Seattle, and one day a man came into the store and asked me a question...I couldn't quite hear him, so I leaned closer and said, "Pardon me, could you repeat the question?"
He leaned in very close to my face and repeated it, and this time I heard every word, which I will never forget: "My ancestors killed Abraham Lincoln. It haunts me still. Do you know where I can get a bucket of chicken?"
I'm not good quickly identifying people with emotional problems, apparently. ; )
(I pointed him to a Subway sandwich shop across the street, and he left.)
I told him I was an engineering student and didn't have time for pleasure. He laughed, the spell was broken, he could BS me no more and I moved on to join my friends up the way.
