Personally, I'm a very odd ball in the situation. I believe having and open mind to mend old wounds is the first step to bettering yourself as a person. By bettering yourself I don't mean "I'm a good person everyone loves me." i mean coming closer to that person you ould possibly want to be. If you want to be a person people likes, if you want to give great advice, if you want to be in a public service job, i you dream of teaching anyone anything, if you desire more from this shit hole we call 'life, and or if you want to be someone of influence in your community having an open mind to those you cannot stand and learning how to 'play it cool' in an environment where they are is paramount.
In my opinion you don't have to go about TRYING to heal your relationship, some folks are just down right fucking ignorant twits who can't see past their own nose (Thus they can't dress themselves proper)! However the "love those that have hated you and done you wrong' mentality isn't a sewage thought. It roots itself back in time beyond religious principle and into the morals and folkway of the past. I'm not saying go around out of your way to be friends with that person. What Im saying is there's no point in you walking around like a victim hating that person and the wry sight of them for the rest of your natural life. There's no point in anger filling your heart a 'bad taste' flooding your mouth and your wry mind being consumed by the savage thought of them being happy. A lot of people aren't merely angry with the person that wronged them, they vindictively wallow in the moment that hurt them with the very words brazened in their ears the very imaged burned into their eyes. These are the people who need to forgive, let it go, and move the fuck on with their life. Encouraging that level of hatred only breeds stupidity, ignorance, violence, and mindless hours of thought. You have better things to do with your life than remember why you hate X person, I believe it and so should you!
To me having all these people, or one person, you can't 'get along with' is stupid. I can mold myself and change what I do so that I can not step on someones toes, if they choose to persue me afterwards that's their beef, they're looking for trouble? Then I smite them with fire from above and bellow watch them wallow in the very thing they call an existance and laugh about it later. I watch as their 'freidns' ostracize them , but all in all I did nothing to provoke them and didn't 'summon' their wrath upon me. Otherwise, if they wanna get along I let the inside every aspect of my life, because i don't HAVE to be reminded of that dumbshit you did to hurt me. I don't have to have my mind go back int ime to tat time when you hurt my feelings, insulted my dad, stole my girlfriend, hurt my mother. I assume people grow, change, and become better people than they were yesterday. But hatred breeds hatred, violence begets violence.
Sadly the thought o "Move the fuck on with your life" Has been lost to the nintiees and we instead encourage people to hold firm to their feelings because it's "okay to hate" and it's not. Honestly, so long as you aren't hating a person, so long as you don't despise them, if yous itll don't want them around that's different. That's a personal preference, it could be that y'all just don't share the same tasts and he annoys you, that's fine. But when you ahve to ask them to leave you be, it's clearly more than annoyance, and it's not okay.
I leave with this video of Robert F Kenedy that's quite famous, anyone above the age of 25 has more than likely heard it.
