"That Was Kind of You"

I saw a campus official shoveling snow away from the path this morning, and I briefly thanked him for his work. A few moments later, a girl stopped me and asked, "Hey, did you thank that man for his work?" When I said I did, she replied, "That was kind of you." As she walked away, I thought how nice it was of her to give me those few, kind words.  I am grateful that I was caught doing something kind today. :)
