Tonight I spent 2 hours driving a friend to the airport. My friend didn't ask me for this favor but when I heard she needed one, I offered. When I got home I called the real estate agent for the house across the street (the family has moved out) to let him know that the garage door was standing open and anyone could enter the house. He was unable to come attend to the house and he asked me to take care of it as a neighbor and as a favor to the family. I did so happily.
