A Letter to Penpal

Dear Mike:
How are you?
As news reported, H1N1 flu is spreading. I hope you and your family are all well and healthy.
Do you have to go to school these days? I propose you staying at home as far as possible. And reduce the contacts with others. Remember to wash hands frequently, open windows to keep air fresh daily, and have more fruits and vegetables than usual.
As the flu is not so deadly as it seams to be. Don't be nervous and take it easy. In a good mood is greater than whatever.
Sincerely.
