You're walking along one day, and you come across a wallet on the sidewalk. Upon opening it, you find $900! There's also 2 credit cards, the ID of the owner, who's a woman in her 30s. There's also 3 pictures. The first pic is of a little girl, the second is a little boy, and the third is the three of them.
What do you do with this find? Do you keep the money?
