In response to:
While walking on the beach you stumble on a valuable object buried in the sand — say, a piece of jewelry or an envelope full of cash. What do you do with it? Under what circumstances would you keep it?”
My brief response: I would bury about 10 little notes in envelopes in the area saying that if someone is missing something from that area to email ___________. If I did not receive a response in the next few months I would keep it.
