Some people will never figure out how to be happy. They will never learn how to forgive the past and create their own future. They might never understand or be grateful for the respect you gave them simply because they are a human being. They might always wish you pain simply because they still hurt. I wish there was something I could say, but nothing would change. Not the hatred or petty immature bullshit. Good only ever comes from within. The best you can do is to try to put a little more good out into the world. A little more respect. A little more understanding. And maybe someone else might decide to find their own happiness too.
It’s a big maybe, but it’s worth a shot.
