...I have failed you.

I should have studied more. And I should have not parked my car illegally
downtown. I shouldn't have gotten my car towed, and I shouldn't have taken
a taxi to MRC, and I shouldn't have been stressed out over how much it
would cost to get my car back right before my mid-term.

Well, I don't know that I failed you exactly. But the test results will
not be the best, based on a lot of minor technicalities added together.

But that's a little too many "should have"'s for you, ain't it?

Won't happen again.
