Wow, that letter brought up some bad memeories for me. My father always treated me like he didnt want to be around me. He'd be talking to my younger brothers and laughing and having a good time and when I'd walk in the room, his whole demeanor would change and he'd clam up. Never discussed the gyne with him, never discussed much of anything with him. I will give you one piece of advice. In 3-4 years you will be on your own, and you can pursue anything you want in the way of a career. DO IT. Don't let anyone put you n a place where you are pursuing a career just to make them happy, because you will wind up making yourself terribly unhappy. If you want to open a shop or have manual work profession, then do it if it makes you happy. And do not be afraid to change it if later on you discover that you were wrong and you want to do something else.
God Bless
