It’s sad when you try to be kind to someone

and you feel they are a kind person then they attack you without mercy. There’s a saying: Have mercy on others so God will have mercy on you. Why hate someone without reason? Unless the person truely harmed you then there’s no reason to hate.
When I was very young I didn’t believe people could be soo cruel. I was naive and I learned the hard way how cruel people can be. I’ve seen cruelty way too much in my life and I’m sure others did as well.
