Smile from a stranger

I was driving home yesterday and was nearing my turnoff which was a right handed turn. The light was red and there was a car in front of me waiting to go straight. The driver saw my signal light to turn and moved ahead a little so that I could get by and do my turn. I thought, that was nice of you, so when I moved forward, I caught the eye of the driver and waved and smiled as to say thank you. It was an older lady and she smiled and waved back. That made my day! It's all too often that people get in their cars and lose personal contact with others. They think the car is an exstention of themselves and turn into completely different people. I still smile when I think of it.
