Moral Question

Interesting thing came in teh mail today. It was from "Help Hospitalized Veterans" In it was a $2.25 check. The letter enclosed said that they obviously don't have money to send out, and they hope that instead of taking the check we send them more money.

Is it wrong for me to deposit the check. They are dumb for sending me a check, its a risk, that in this case doesnt pay off. Also the envelope they sent for me to return the check in didnt come prestamped. So I'dhaveto also include a stamp
