LOL. I think this means to become a bully & do as they do. Since when do bullies understand boundaries ? And, why would they listen to their target when they are determined to do harm. Only someone who has NEVER experienced a bully would make this type of comment. Actually, it sounds like something a bully would say - it's the fault of the victim because they cannot set boundaries. The only solution for bullies is to get them out of your life.
