When it snows during the day at work, I like to brush off a few vehicles in the parking lot. It makes me happy to think about someone walking out to their car thinking they are going to have to brush it off and finding it ready to drive away!
The other day when I was at the post office near my house and I told the grouchy clerk that her hair looked really pretty. I'm in there often and she is always wearing a scowly face. It just hit me to say something nice to her, and when I did she beamed and gave me a big beautiful smile. I told her she had a beautiful smile too, and that she should wear it more often. She giggled and said, I will and thanks. As I was going out the door she waved at me still smiling.
That felt good.
