I used to work in a textbook store where a fair number of the customers were high school drop-outs who were enrolled in "adult education" classes. Almost every day, at least one kid would come in with a signed check from Mom and Dad and buy the books required for five or six classes and then bring three or four of them back for a refund the following day.   Whatta ya' think the chances are that they went home and gave the money back to Mom and Dad?   

The whole concept of ripping off one's parents is so foreign to my way of thinking that I can't even conceive how anyone could bring themselves to do it. They must really hate their parents.
