To be a hater as an adult, you have to have some deep rooted issues you refuse to heal from childhood. There's no reason your brain is fully developed and you hate to see others doing well.
I don’t want revenge, and I don’t want to forgive you either. I just want you to live with the weight of what you did to me and, one day, finally understand the pain you caused.
When someone is secretly envious of you, they think that every little thing you say or do is a jab towards them. You could literally just be breathing and they will take it as a personal insult.
