早沾勿药

Dear Mr XXX,

I am XXX's mother. My son is your year 4 class ABF+PR student. He is having a heavy flu. The doctor suggested that he should stay at home for a couple of days. Therefore he won't be going to school on April 26 to 27. Very sorry about that. But he will be back as soon as he gets better. Best wishes!

Yours Sincerely,

XXXX

重感冒是 heavy flu

大伤风是 heavy clod (本人居於英国，病名翻译准确)

希望你早沾勿药，快快康复，和学业进步!!!
