What do you think of me not a nice person?
That wouldn't be good. Can you tell me more about why you think you're not a nice person?
Most people would describe me as an obnoxious bitch
I hear you, but it is definitely very important to be nice to other people. It helps build relationships for life and you should try being more considerate of others. Otherwise you will end up alone and forgottten.
I forget what is the point of good behavior. I want to make people feel uncomfortable.
The point of good behavior is to be kind to others and so they will be kind to you. Life is already hard so why make it harder on others by not being kind to them.
