Dear Miss Lim
Please accept this letter as my formal apology for what happened on computer lab for being late on 9th September 2012.
It was not my intention to cause any damage or inconvenience. In retrospect, I believe the situation resulted from not concern about the English blogging. While this is by no means an excuse for late for class, knowing the cause will help me guard against future mistakes.
Again, I am sorry for what happened. I look forward to hearing from you and putting this matter behind us.
Sincerely,
Marcus
