小学预防春季传染病致家长的一封信
来源：好兔宠物网
Dear Mr. / Ms,
Last Friday, when we were discussing the problems of defective containers. You suggested that I simply mail you a report each month on the number of return by customers rather than send the defective containers to you.
I plan to put this into effect at once. But, I first want to make sure that I understand you correctly. If I don’t hear from you within the coming week, I’ll assume that you approve.
Yours faithfully
