原谅我的英语水平只能写出这样的了

Dear Li Do not worry, you can try to talk to him, tell your heart distress, let him stand on your point of view to consider, you can listen to music, but there should also be a time limit, you can, and he said late at night listening to music is not only bad for your body but also affect the rest of others. I believe that if you are patient and talk to him, he should be considerate. I hope my advice is useful. I wish you good luck.

Dear Jerry,
I'm sorry to hear that you can't sleep well because of your roomate's behavior that he often listens to music at dead of night.In my opinion,communication is play an important part in our life.
Only you tell him what you think about it do he will realize his mistake.To begin with,you should not only be brave to talk with him but also try to let him make sense of you.Then you discuss with him on how to deal with it and both of you two should obey the rules drawed.
Looking forward to your good news.
