　Dear Tom,
　　I can understand how you feel.When I was young,I had the same experience as you do.I often with parents fight for my studies.But after I talked with my parents heart to heart,we had a better understanding of each other.So try to communicate with your parents to let them know that you are wise enough to manage your own business well.To understand them better,always put yourself in their position.Don’t you think that all parents in the world love their children even though they are sometimes strict and serious If you can spend your time and money more wisely,I’m sure that your parents will trust you and you will enjoy more freedom.
　　By the way,it’s understandable that your parents ask you to put your studies in the first place.
　　I hope my advice is of some help to you .
　　Yours,
只有这个了，麻烦才拿一下
