I really can't stand my dad. He is a fat slob.
Why do you hate your dad?
He's just a useless clod of flesh. He thinks I was born to support him.
I'm sorry that your dad is not very helpful, but you shouldn't hate him. Spending your time hating people like that will make you bitter.
He disrespected me when I bought the car and I'm going to get my revenge on him by humiliating him. I'll show him what's really happening.
I get that you're going through a lot with your father but going out of your way to cause him emotional distress isn't going help the situation. You should have a one-on-one conversation to try to talk about the issues you're having and see if you could fix them.
