Replying to MAD DADS?

My father always seems to be mad and it brings my mother and my sister down. He rages at the smallest of things for instance, dropping a small piece of carrot on the ground or not wiping off that one droplet of water on the finished dishes. Yes, we don’t have a dishwasher.

I work with him 5 days a week, 10 hours a day and go on gigs with him on the weekends. One thing that i’ve notice is that at work he has this amiability that he never expresses when home. Maybe this is because he is a pepsi addict. On a yearly average I calculated a consumption of 1120 16oz pepsi bottles. When he is deficient in pepsi he acts like a coke addict going through withdrawals and rages but usually this never happens because he buys in bulk. Nevertheless, when he reaches dat pepsi high no one can keep up with him. He runs around like Usain Bolt on crack, but when he has to multitask he gets all mixed up and is as useful as a screen door on a submarine. He leaks often and it sucks because now he has to pay to visit the doctor because his insurance doesn’t cover it.

Any who, he comes home from a long day at work and starts raging like crazy. I try to help him, I do everything I can but it is no use. Nothing is ever good enough for him. I make him his favorite lentil, carrot soup and he won’t eat it because I made it even though it is already pre made. Is this subconscious, does he have some kind of OCD, affair?

He isn’t mad at me nor my family, he seems to be mad at himself and I wish I could talk to him as a friend, as a therapist but I’m a pussy.
