How do you know if they hate you? Have they told you? What behaviour indicates to you that they truly don't want to know you or are "faking" it? Different people have different social styles. While one person may like to associate with many people on many different levels, another person might consider socializing as more intimate and fewer people and more all encompassing. I had certain groups of people I associated with at certain activities. There were the people I went swimming with, the friends I went dancing with, the friends I worked with, and I never crossed either group with another. I enjoyed the company of each and every person in that environment, then went home. None of them were fake.
