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
