Actually yes, just two days ago. I went out for my daily walk and a woman on the other side of the street smiled and waved to me. At first I thought maybe she thinks I'm someone else. But she crossed the street and mentioned what beautiful mild weather we were having for January. We stood around chatting for a bit, wished each other well, and off we went.
During the rest of my walk, my mood had changed completely. I kept thinking what a nice person, and how nice it felt coming from a complete stranger! I made a mental note that I will have to pass this on one day to someone else.
