If you find a $100 is it your to keep ?

I would have a bad feeling about taking it.  I would convinced myself to find out who it belong to.I am not one of those people that wad it it up and put it in my pocket.  Putting it in my pocket is not a decent person.  I don’t find out who it belong to yes I will keep it.  But I wouldn’t spend it on stupid thing like finger nails and etc.  So I am kind of in the middle.
