Dear Mum:
Happy Mother's Day!
I don't know what I can do for you on this special day.The only thing i can do is to write a letter to show my deep love for you.
Without you I can't grow up happily like others.Without you I can't study in such a nice school.You have been working so hard to pay my study.You have to do all the housework in order to save time for me to read.You're wearing old clothes to save money for my further study.Thank you very much for all you have done for me .
Mum,don't worry about me.I will work hard and be a good student.Take care and be happy!
Love,
XXX
