Last night I told my dad that I hate him.
Really? Why would you say that to your dad?
Well, I fucking do hate him.
Even if you dislike your dad, telling him that you hate him won't help the situation. It will only make him feel bad and cause tension between you two. If there's a specific issue, you should talk it out so you can improve your relationship.
My dad is the issue. I hate him, and have no reason to talk to him.
I really think that talking to your dad about this issue would be good for both of you. Just telling him that you hate him and not speaking to him will only lead to tension and even more animosity.
