Bob, the artist nearest me, said "It's never a good sign when you hear paper being crumpled up during a pose."
I said "Yeah, that was a defective sheet of paper. It didn't draw good at all."
At the end of the evening's poses Bob ripped several sheets out of his sketch pad, folded them in half, and said "Anybody want to buy these before I throw them away?"
I asked "How much?" and he said "Three dollars."
"No thanks."
Then Bob ripped the sheets in half, handed one of the halves to me and said "How about $1.50?"
Oh how I wish now I had bought the ripped-in-half version for a memento. Maybe I'll have another chance.
