One year my uncle decided to cheat on his income taxes. The problem was that he later started to feel so guilty that he couldn’t sleep. After thinking about if for a while, he sent an anonymous cashier’s check for $100 to the IRS along with a note that read:

To Whom It May Concern,

I cheated on my taxes and now I feel so guilty that I haven’t been able to sleep for weeks, so I’m sending you this check for one hundred dollars. I hope you forgive me.

P.S. If I still can’t sleep after one week, I’ll send you the rest of what I owe.
