School issues

In school, I have a friend, who I will not name, that is made fun of because she doesn’t shave. They turn her name into a pun about needing a shave, and they actually laugh about it. What kind of inhumane monster could ever judge a person by how their face is groomed? It is HER face, and she can do with it whatever she wants. Any time I hear this kind of attitude, I want to get violent, but I don’t. I do, however, point out what they are doing, and ask them what they gain from talking about her. I refuse to hang out with any I hear talking about her. I am one who is slow to anger, quick to calm, and I cannot hold grudges against one who has wronged me. Even with all of what I have said, I am angry, will not forgive them until I have a reason to. The only reason I hold the anger is because it is not wrong to do so. This is righteous anger, and I will not allow anyone to talk bad about another around me, because I used to be on the other side of such talks.
