Book worm hole

Some people think out loud when they’re deciding whether or not to buy one of my books. Whatever they say that they will do with the book, I agree (as a closing tactic).
“I’m a personal trainer. I would use it as a teaching tool.”
“Good idea,” I say.
“If I bought the book I would flush it down the toilet.”
“Good idea. It’s a clog buster.”
“If I bought the book I would take it to a book burning.”
“Good idea. You have to stay warm.”
“If I bought the book it would just sit on a shelf and collect dust.”
“Good idea. Maria has to have something to clean.”
