It's very rare that one of the fights actually hurts me . But I'm not too great with apologizing either , especially when I'm not sure what I said to make them angry . Usually I know when I crossed the line . Today , I crossed it but am not sure exactly where it was drawn in the sand . See , I was talking to my friend , who is like an older brother to me ( in more ways than one , he's always been there for me since we met ) , and there were a few things he kept joking around about that made me uncomfortable .

Why is my friend like an older brother to me ?
