I always have an opinion, but at work I only expressed the ones about the work. When my youngest was 12, she summed it up very well. She was on the track team and throwing discus and shot put. A girl who also was doing those events was generally not liked. My daughters' friends asked her how she could stand being with the other girl every day for 2 hours.
I was proud of my daughters answer. "Well", she said, "If you have to be with someone every day, it's much easier to do if you like them."
She and the girl became friends, not close, but friends. They keep in touch over FB, even now, 20 years later.
I liked the girl, too. She was "rough around the edges", as they say, but basically a good kid. Years later my daughter told me that the girl had lots of problems at home and had a very hard time with school. I like to think my daughter's friendship was very helpful to her at the time.
