What kind of books, magazines, newspapers do your grand kids read? What did you read while growing up?
When I was volunteering at two Palm Harbor Libraries back in 2000-2003, I never made any bad comments about whatever some library user was checking out. If they wanted to check out a book on the particularities of farts, then Benjamin Franklin would have been made happy as he wrote an satirical article on a similar topic.
