I'm sorry for emailing you excessively. While I never whined or made demands, your time is precious and I took up too much of it. I'm sorry for skipping class and then asking you to rehash what we did while I was gone. Again, a waste of your time.
Although I can't take back all of the rude, arrogant, inconsiderate things I have done in the first three years of my college education, I promise that for my last three semesters I will be a model student. Or, at least, I'll stop pulling the dumb shit I have in the past.
