My father and I always argue.
Once he was dissapointed that I did not go out very much, that he hoped I would be more like him. He called me the biggest dissapointment of a son a father could have.
Or when my parents fought and it was about me. He said to me. If we ever were to split up, it will be entirely your fault.
I don't hold a grudge, but it is something I will always remember.
