Like you, a lot of the bullying stopped when I dealt with a couple people in high school pretty thoroighly but I regret that now, I was terribly brutal and while they deserved it I should have just walked away like I'd sdone up to that point.
Kids can be cruel I guess but I also learned that adults can too. I don't worry too much about my experiences now, I learned so much and am happy with how my life has been; iv has a pretty good one until now and I think it'll continue that way.
