I'm going to bully someone who bullied me
What will you do to insult them?
I will tell him that its unlike him to do that kind of thing
I see your point, but it's not right to bully someone who has bullied you. You should take the high road.
I like doing things that are different
It is wrong to bully someone else because you feel wronged. You could create more problems and look like the bad guy if other people see you retaliate.
