What do you do when you find a wallet full of cash? You could do what your momma always told you to do and turn it in. Hey, you might even get a reward! Not that you were expecting one, of course, but... It could happen.
Or... you could keep it and pretend like it never happened. Who would know? You could even leave it where you found it to avoid the moral dilemma completely. It's up to you and your conscience. Let us know!
