At first, I was like, "What? Of course!"...then, I read a few posts.

My manners (or lack of them) reflect on ME, not others. So, while I try to exhibit good manners at all times, when someone else doesn't- I don't get rude back. I have held doors for people that have 'forgotten' to thank me. So what? I am holding the door for them because of my upbringing, my manners. Not so that I am thanked in return. Same with greetings on the phone. I almost always say, "how are you" or some other polite greeting. Some people don't ask me the same thing. That's okay. I have manners, I help make the world a nicer place. They don't. Their shortcoming. Not mine. And, to point it out is rude, the very thing I am trying NOT to be.
