I was ridiculed

I am a bit extroverted and I don't come from a so called elite family. I met my boyf's friends the other day and felt really very sad. Apparently I am loud, lack manners and behave cheap. I am not loud, I am expressive and don't think that's a bad thing, and don't know what does being cheap mean. I am hurt not because of what they say, but I feel I can't fit in with these set of people. They are obsessed with fitting in the social norms, overly judgemental and name call people. I am free spirited, extroverted , loving and never been so judgemental and can't conform myself to all these bullshit, don't know if I am being the so called cheap, but it is what it is. Why are people these days so nonchalant and entitled ? Why can't we just live our lives to the fullest without getting judged or indulge in judging others like they ate some supreme beings ? I see people saying they can't make good friends or fail to make meaningful relationships, I now understand why that happens because everyone is so rigid minded , judgemental and has this Supreme better than everyone complex, they care more about what others think of them instead of truly living and enjoying their own lives. It sad because it hurts both the parties, you are submitting yourself to bullshit and making others guilty for being the way they are. These people are extremely castiest and classist, they are the ones that preach you to be a better person and mindful bullshit and act very nice good sweet adorable , I can never stand these hypocrites.
