Say Please and Thank You

I read somewhere or heard that it's very important to always say "please" and "thank you." It sounds simple, but there aren't enough people who practice such good manners. I was prompted to write about this after I let a car (an SUV actually) turn in front of me so the driver would not have to wait in several minutes of traffic. The least the driver could have done was acknowledge my act of kindness and throw up a hand to gesture thanks. That did not happen. I wasn't angry, but I was a little disappointed that no appreciation was signaled. Maybe this person was having a bad day or justa bad moment, but it doesn't take much for most of us to wave our hand. I have learned that "please" and "thank you" will take one very far.
