I have found wallets before. Never, mind you, 
with $200 in them. Usually around $50. If there 
is any, and I mean any, way to return it to the 
seller then I would do so. If not, $50 goes to 
the Brian Lowery college fund. How do you know 
the guy was a traveling businessman. He could be 
some poor schmo like my cousin from Australia 
visiting his folks in the states. Maybe you just 
took his only cash so he could take the train to 
his parents house or something. Either way, you 
are stealing. Possession is 9/10 of the law only 
when there isn't an ID on the damn thing you are 
trying to possess. If you need to pay an electric 
bill or something, I could see your point. But to 
just blow it on a cel is childish. If Mr. 
Insurance Man was coming to take my car away and 
I found $200 in wallet, I wouldn't be as picky 
about this. But to just use it to buy a cel, 
c'mon. You can rationalize all you want, but 
someday you are going to lose a rent payment or 
car payment and then see how much praying you do 
in the hopes of getting it back. Or maybe you'll 
rest easy knowing the thieving bastard has bought 
himself a stack of porn or some X-Men comics with 
it.
