My dearest Mother,

　　The mother's day is coming and I would like to say "Happy mother's day" in this letter. I love you and thank you so much for everything you did for me. This day, I will stay away and can't give you my appreciation at home. I know I will watch myself, so don't worry about me. I am doing very well on my study. My schoolmates and teachers are all very nice. Though I can't be at home, I hope you have a wonderful mother's day.

　　Love,

　　Your son
