You, Enid, Ron, and Carl had a small friend group

You used to be really close, until this new girl, Lily, joined.

She tried to separate you from them, and it was working, they had grown cold and distant with you, and only acknowledged you when they were bored or when the group wanted to hang out.

Ron had noticed how sad you had been, but he didn't say anything.

About three weeks later, you were all in Ron's room, talking and reading comics.

You were all sitting on the floor, and as you reached over Enid to grab a comic.

Ron saw that your sleeve had lifted slightly, and he froze as he saw a glimpse of red lines. Everywhere.

You, Lily, Enid, and Carl didn't notice your sleeve lift, and you just sat there, while everyone conversed.

It was then that Ron realized why you did it. He realized how much they left you out, how much they insulted you, how much they 'joked' around.
