I hate my dad for buying me a car
Why are you mad that he bought you a car?
It was not the one that I wanted.
A lot of people do not get cars from their parents. You should be grateful that they got you one at all.
Easy for you to say, but my parents should buy me the car I want.
Well, when you get older you can buy the car you want. In the mean time, you should be grateful for the gift you are given.
