Train of Thought

"Mom? Can you buy books at the library?"

"Our library actually does have a used book store upstairs, but usually you just borrow books from a library."

"Well I think we're going to have to figure out a way to buy The Hobbit. It's long and we're not done yet."

"That's okay. We can re-new it."

"Oh, that's a good idea... also when you cut my fingernails at nighttime I think we should call it finger-night."
