Нужно перевести в косвенную речь и именно с прошедшим временем1. Hi, my name’s Sarah and I’m sixteen. My father’s making my life so miserable! I used to get on so well with him, but these days all we do is argue and yell at each other. He’s so strict and has these really old-fashioned views. He won’t let me date boys, he won’t let me wear make-up, and he always says I should learn to behave and treat him with respect. I wish hed just let me alone, but how can I make him understand this?
