These are so true! I was out shopping a few weeks ago and when I got out of my Jeep I put on a pair of sunglasses. The people in the truck in front of me were smiling so I smiled back. Then they started outright laughing. I just smiled and went on into the store. Once inside I no longer needed the sunglasses so I pushed them to the top of my head, only to find another pair of sunglasses and two pair of readers already resting there!
