Some people find reasons right from the beginning to dislike you, without having one convo or interaction. Those people are the ones who need to look inside themselves and discover what internal battle they are fighting.
I've learned the hard way that most people either don't want to understand or just can't. So I stopped trying to make them. It is my journey, my pain, and nobody else gets to tell me how they think I should be handling it because they're not in my shoes.
It's funny, because I read this as character being a person in a story, not like what you are... I'm not switching. So, may the characters you write, preach more loudly than the descriptions that are placed around them. Meaning, write good characters ;)
