Wave at people. Let them know you see them. You may not think you have time to stop and interact but you can wave and acknowledge even people you don’t know. It’s a good thing. Kids love it. Well, most kids. Just a little bit of connection can give a lift to an otherwise hard day. We never know when one little act of kindness can change the direction of someone’s mood or happenstance. We do know it can also change our own attitude.
