Dear Kevin,
Thank you for your letter. I was glad to get a letter from you!
You said me that you were in the hospital. What a pity!! Are you OK? Oh, my friend Elmis also was in the hospital for two weeks. Fortunately he is doing well and he is already at home. I visited him every day.
Yes, I can give you advice. You must obey doctors, eat well, comply with hygiene and often go out to get some fresh air.
Are your parents visit you? Do you want me to come too?
Oh, I must finish my letter. Get well soon! Goodbye !
Best wishes,
