You're in a thrift store looking at some books on a bookcase. Next to you is another bookcase and a woman is sitting on the floor looking at the books on the bottom of that bookcase. You flip through a book laying on top of a pile of other books on your bookcase and decide to purchase it so you put it in your basket. You continue to look at the books. The woman stands up and begins looking around and then says, "Did you pick up that book?"
"Yes I did," you reply.
"I was going to buy that book," she says. Awkward pause. "I put it there while I was looking at the other books."
So.....Do you hand the book over to her or do you keep it?
What do you think?
