In high school, there was a kid that was a little nerdly, a little quiet, kind of tall, and maybe a bit socially awkward. Nothing severe, but noticeable. I worked at the grocery store in town at the time, with a couple of boys a grade above me. Anyway, this quiet kid gets a job there too. And the vultures started circling. One night at closing time, me and one of the other veteran courtesy clerks were walking to our cars, while the new, quiet guy was walking to his car on the opposite side of the lot.
The veteran courtesy clerk started in with a scowl, saying "What do you think of that new guy?" The message was delivered with facial expressions and tone of voice. The right answer would have been, "Yeah, I don't know about that guy. He sure is weird (or he sucks, or whatever)" Instead, I had a sudden inspiration. I understood what a divisive, vile personality my companion had always and exhibited and decided it would stop here. So I said, "Oh, I really like that new guy."
I turned and walked away from that sour fellow and crossed the parking lot to where the new guy was parked. Basically I became friends with the new guy, and added him to my "circle". The friendship lasted several years. We're still friends, but haven't seen each other much since highschool. But I'm relatively certain that it made a difference in his life. He became much more outgoing, and I believe he enjoyed the last two years of highschool much more than his first two. Kind of no big deal, I know. I tell the story because I remember the turning point, one rainy night in the parking lot at Thriftway in Veneta, Oregon.
