This year in my linear algebra class, we took a test. It wasn't really a hard test, but it wasn't all that easy either. I was surprised, however, when I got my test back and there was a score of 63 (a "D") on it. My first thought was, "Geez, I guess I didn't know my stuff." But, upon further investigation, I realized that I am just the retard I've always known myself to be.
On the day of the test, our teacher told us to not do a part of a problem. I was not listening totally, so I crossed out the entire problem. That question was not all that hard, but by not doing it, I lost 15 points. With that problem alone, I would have gotten up to a "C+" easily.
The other problem that I screwed up on was the last problem. I worked it all out (but didn't show any work) and got to the answer of zero. But instead of putting "0" as my answer, I decided to put "none." I'm not sure why I did that, but I did. With that answer and the one before, I'd have ended up with a "B+" instead of a "D" on the test.
So, you see, even when I have the chance to feel less retarded, I somehow sabotage myself out of it. That is the mark of a true retard.
