<human>: Give me a shortened version of the text

I'll start, when I was in highschool, grade 9, I had a started with a very close nit group of friends, around 6 of us. We had all gotten to know each other the previous year in one class, and before then, I honestly had 0 friends, so that year in grade 8 was a great one for me. 

So anyways, throughout the first year of grade 9, we would all meet at the start of the day in one location, relatively away from populated areas, and just hang out and talk before school started. Eventually somehow, and I'm not sure who suggested it, but it was brought to my attention that we were apparently considering not hanging out with one of our group members. I have no idea how this came up, and apparently we somehow made a consensus, so our one "friend" at the time, who we could see walking across a large field to get to our hangout area, would start to approach, and we just migrated away from wherever he was, he would cut us off, and come in a side door to the school or something to meet us, and I assume he figured we were just moving somewhere else each time. Eventually he started to figure it out, no one was really talking to him, we got quiet when he showed up, etc. He stopped meeting us at the area after a bit, and much to the relief of some of the other friends in the group. 

 I have never felt more disgust with myself than at that time in my life, I just went along with the group, and didn't question anything because I wanted to belong I guess. Low and behold a year later we ended up deciding to do it to someone else in the group, and the same sort of thing happened, except I continued to purposely hang out with said excluded friend because I still like him, and I didn't want to feel any worse. Eventually I figured out who was making the decrees to exclude people, and stopped communicating with that person. The group kind of split in to pieces, and I'm glad I'm still friends with the people I am. So that's the most ashamed I've ever been of something I did in my life, and I ensure that I won't repeat it whenever I can.
<bot>: Had medium group of friends entering high school, as a group we somehow decided to cut off communication with one specific person, I felt like a dirtbag for going along with it.
