This isn't so much "I didn't like" as "I didn't know them and they were totally in a separate group than me".

In middle school, I was bullied pretty badly, although it was mostly verbal (perhaps since I'm a girl). One day at lunch, I was being bullied in the lunch line, to the point that I start crying. I'm humiliated by the fact that I'm crying in line, in front of everyone, but lunch is so short that I refused to let them chase me away without being able to eat. I also didn't want to face a teacher's wrath by leaving the lunchroom, because we were not allowed to leave. So I go through the lunch line, tears silently going down my face.

There was this one girl, a redhead, who had a sort of reputation as being...more mature? Harder, maybe, than the other girls? Basically, the type of girl who probably listened to metal, and whom the other girls would start up a rumor about being pregnant, or goth, or whatever. I recall her wearing the hairstyle that's popular now, with the shaved back and sides and long top...and this was in the mid 90s, and really wasn't worn by girls in middle school in our area at that time.

But she came up to me, and sat down with me at lunch, and offered to comb my hair. Out of all the people in the lunch room, this is the girl that showed me kindness.

And I actually found that to hold true later, in high school, with another group of girls who let me be on the edge of their group (when I literally had no friends). (And I was mostly only on the edge because I was walling a lot of people out just to survive my home life...had I been more open I probably would have made some good friends.) The girls from preppy homes or nice homes were, perhaps, tolerant or superficially nice, but when shit went down, it was the girls who were seen as "bad" or "broken" that showed me support.

My guess (after learning a bit about some of their home lives) is that they had crap going on at home, and had learned something from it that kids that were going through more "normal" teenage experiences didn't have. But it also maybe made them have more empathy I guess, or at least show it towards me more than most girls did.

And that's sort of why I always see folks with the grunge/rock/metal/tattoos/piercings in a positive light, because that group has tended to abruptly reach out to help or lend support. And they didn't have to at all. But they did.
