positive attitude

I picked up my son today to come home for his fall break. We talked some in the car and at one point I complemented him on his positive attitude and asked him if there was anyone at school he didn't like. He said there were a couple of people last year but they didn't bother him as much this year. I asked if that was because they had matured or he was more tolerant and he said they must have matured. He describes himself as not social and doesn't know how to make friends, but at least he has a positive attitude about people.
