要写得得体啊Dear XXX, I am so sorry that I was late to the class this morning. Although it because that I missed the bus so that I had to wait another 15 minutes for the next one, I still need to take the full responsibility for it. If you would accept my appologize, that would be great. I promiss you that I will not be late to any class again. Yours sincerely Tony Blair
