Dear Ken,
I know you have been ill for quite a few days,and your mother told me you don't feel well now.I understand you,for you have to be in hospital and have to take so many madicines.But I'm sure you can overcome all these difficulties.What is more,all teachers and classmates care you.I'll go to the hospital to see you after school,and help you with your homework.We believe you will get well very soon.
Well,just take it easy!I'm looking forward to seeing you at school.
Yours
Jack
