How Do You Handle Negativity, teasing, being picked-on and nastiness from others? Also BLAME??

I hate these kinds of situations with a passion!

Anger and confrontation are NOT my preferred forms of communication. Yet there seem to be people in my life who thrive on these kinds of things. They "pick" and they "tease" (sometimes excusing themselves right afterwards, with "Oh, I was just teasing." and sometimes not).

Then, when one of these someones acts like the victim, because I went to a person in a position of authority and complained about their mistreatment of me, they blow the scene and tell everyone it is my fault that they left. *I* was supposedly trying to get them in trouble. All I did was ask that the person in charge advise them NOT to pick-on, tease, or in any way bother me.

With another such person, ONE TIME, I decided to pick-on her and tease her back. WELL! She did not like that. So, she can dish it out, but she sure cannot take it!!!

The first person has taken NO RESPONSIBILITY for their mistreatment of me (and others). He just blames us "for trying to get him into trouble." He never apologizes. He never admits any wrongdoing. It is always someone else's fault.

I have run into this thing during other times in my life also. It is maddening. It seems to be some kind of thing that you cannot fight back against either. The attitude is something like, "What is the matter with you, can't you take a joke?" Well, how can I take it as a "joke" if I can't see the humor in it? In other words, I am being made to be the BUTT of the joke. How is that going to be FUNNY to ME?

Sure, it is funny for the person who is dishing it out. Sure, it might be funny to others who are listening to it, but for myself and the others who are being picked-on, called names, told nasty stories about, and in general being mistreated, it is NOT funny, fun, or any other good thing. It is painful!!!

So, what do you do when this kind of thing has happened to you? Or has it ever even happened to you? Also, what do you do when you see it being done to others? Just curious....
