I heard the coolest story the other day.
A friend of a friend, years ago, was driving down the Freeway in LA when he saw a very good looking well dressed Black woman who was pulled off on the side of the road, obviously in need of help.
He drove his car off onto the shoulder and ran back to where her car was parked, and found out she had a flat and didn't know how to change the tire (this was before cell phones so she couldn't just call for help).
He changed her flat and was about to take off when she insisted on knowing how to contact him -- she wanted to show her appreciation.
He told her he didn't need any acknowledgement -- he was just happy to have been able to help.
A few days later a big-screen color TV was delivered to his home. He couldn't figure out what this was about and told the delivery person that this was obviously the wrong address - he hadn't ordered a TV. But the man pulled out a letter and handed it to him.
It was the woman whom he had helped.
She thanked him again for being willing to stop and help her.
And the letter was signed "Mrs. Nat King Cole"!
