Anyway, I told my girlfriend that I was hearing him speak, and she said, "Hey, ask him how come I can't sell my TV."
So I did.
I waited until after he was done (he was nice, nerdish and charmingly odd, BTW) and approached. I congratulated him on his speech, and asked if I could ask him a silly question. He said sure.
"How can I sell my girlfriend's 19" inch SONY TV?" I said.
"Is it flatscreen?" he asked.
"Hmmm.... well, tell the truth about it, and lower their expectations. And maybe be prepared to give it away. There are better TV's than that for free on Craigslist," he said.
Well said, Mr. Newmark.
