I do to the people who look trust worthy. No, I don't just look at people and think I can trust them not to buy drugs,drinks,ect. But if they have children I do. Once in Washington there was a guy with a dog and the dog was very skinny. It was the guys and he said he wanted to buy food for the dog. I knew he did because after a while the man went inside a petstore. It really was nice to see someone care about his pet more then himself. He didn't look at his best, let me tell you.
