(Hypothetical question) Only honest answers please.
You have a spouse, and two children. You just lost your job. You're out at Wal-Mart because you need to pick up a few things before heading home, and out in the parking lot, you find a ladies purse in an empty cart. No-one is around so you go pick it up. You look inside, there's no ID, but amongst all the crap, you find a $100 bill. What do you do?
