Aww Sarah..I love you dude! Would it make you feel better if I started to online stalk you? That makes everyone happy.

Really though, you're a better person then I am. I try to do these things (like always letting people make left hand turns) but when they don't do it fast enough I get aggravated and nervous that the people behind me are going to kill me so I just go. And always opening the door for people? When they don't say thank you it always upsets me. Like, was it that hard to say thanks? But when someone holds the door open for me I always make sure to smile and thank them so they don't feel bad.

You're probably making someone's day every time you do something nice. Isn't there some little short proverb-story thing out there about this? I think it's in the chicken soup books. There were two, one isn't a proverb-story thing:
-A girl was working at a drive-up coffee/donut place (and now I'm gonna make up the rest of the story cause I can't remember) and one day one of her usual customers was having a bad day so she gave him a free donut and a smile. A few weeks later is was raining and she was all wet from having to stick her head out the drive up window all day. The guy drove up and..seeing that she was having such a bad day came back later with a rose and a tip for her!
-Someone was nice to a homeless man and gave him money..homeless man was happy and bought food..he saw a stray dog and gave it some food and took it home to the homeless shelter. The shelter caught on fire that night and the dog saved everyone. See the moral?
