Actions designed to hurt yet disguised as jokes...IS a form of abuse.
To a person going through this:
It may be hard to take control when this happens to you but always keep in mind that a person never looks good who is trying to make you look or feel bad. People will see this and when you take the high road you take away their power. Finally, seek out the kind of people who would have your back if they see this is happening to you, those are the bonds that will also help you get through this. If you are a bully: Kindness and Love can bring great friendships and joy. An Experience you will never experience if you keep on this path. Think about that for a bit.
