Write a letter to your English-speaking friend about your school life

Dear Mark,

Thank you for replying back to me in such a timely manner. I really appreciate it.

Today, I wanted to talk more about my school life and just how the things go on, in general. First of all, I would like to indicate that the school keeps bothering me for a while with its rigorous academic load; I simply dont have any free time for the leisure. Secondly, I keep getting bad marks and my parents are not really happy about it. Finally, I am just tired of everything and want to graduate now.

Hope I dont complain too much.

Best,

Anton
