Merlin, I have an issue with my dad that's only related to yours in the sense of it's a blow to the relationship. I have found that if I can express my thoughts to my dad in a rational manner when I'm in a good mood, it's very helpful. Bad moods are no good for this cause the conversation can lead to a fight and things could be said that aren't meant. Just my opinion. Hope it helps. Take care friend.
