his mother's son

I noticed that there was a request form on one of C's library books from school. While I have the public library set aside virtually all of our books for us, I didn't even know C could do that at school. Turns out he saw the book at the book fair but couldn't afford it. I'd like to know whether he pitched a fit and the staff found a way to appease him, or if he came up with the idea himself.
