I'm getting the urge to distance myself from my father.
Why do you have to distance yourself from him?
I've been putting up with him for too long.
You should be a better child then and work the problems out with him. Parents and children are supposed to bond and be close, not distance and angry. He may not have much time left so you don't want any regrets.
Old people are a nuisance. I don't care if he dies on me.
Family can be overbearing sometimes. Think of how you would feel if he was actually no longer here with you, is he really that bad? I think you should take some time to think on this and it may change your mind.
