What would you have done?
No one knows what they would do until faced with the situation. I would like to say I would return it and I think I would but it did not happen to me. I try to "do the right thing" but sometimes the right thing is subjective. Character and leadership is what we do when no one is looking. Cliff notes version, until it is your dilemma, you just don't know.
