I know exactly what you mean.
Some people are just born hypocritical and prejudice (< if you know what I mean) especially when people have said nasty things to me such as, that it's not my fault that they have found me annoying in the past when they know I can't always help myself. They say they don't hold it against me but they do.
I mean, how can someone expect you to not take offense, when they're disliking something about you, that you can't always help. It's not like I chose to be this way. Have a bloody heart for Christ's sake, it's not like everyone's perfect.
Secondly, what pees me off is when certain people make snide and nasty comments about someone's appearance when they are in no position to judge. I mean some people are just nasty, shallow and insecure that they project their own insecurities onto other people, to make them feel worse, so they feel better about themselves and their rubbish lives.
Suddenly, I don't feel bad at all.
