I am kind to just about everyone as a general rule. It feels good after. Until you meet some jerk who just wants to ruin it, but that's only every now and then. One story I have is this. It happened over a year ago.
I was in the grocery store lobby waiting for my parents to finish paying. An old woman dropped the change she was holding and I helped her pick it up.She was Asian and had an accent. I almost didn't understand her when she asked if I could order her food over the pay phone. I did it for her and after she shoved a dollar bill into my hand. I tried to refuse, but she insisted. I felt so warm after because I knew she would not have wanted to order the food over the phone with her accent. I refuse to spend that dollar. It is still sitting in a glass bottle on my alter. Every time I look at it I remember that event and smile.
Today I did what I usually do to be nice. I held the door for my classmates when I walked out of a classroom. I only get a few mumbled thank you's, but I don't care.
Another thing I like to do is Free Hugs. This is my favorite. It is so much fun. I haven't gone out in a year, but hopefully I will get a group together and we can go out before snow flies. To me this is the ultimate act of random kindness. A hug can do wonders to help make someone feel good. I encourage other people to do this! (Not alone unless it is a very crowded area and you feel safe. I would not go out alone even though where I live is a safe place.)
