strange goodwill

So, a couple of months ago I was walking on Washington St. and found a check. There was an address on it, so I sent put it in an envelope and mailed it back to the person who lost it.

Then today, I opened my mail, and inside was a nice note and a $20 bill from the guy I sent the check back to.

Isn't that nice? He has no idea how much I need this $20 right now.
