terrible night!

I had a quiz for my operations management class on Thursday night. The quiz is really not that big a deal, but I wasn't able to understand the whole class before the quiz on that night!!! Not even a sentence!! When the professor asked us to separate into groups to discuss the questions on the textbook! It was a much more tough time!! I could just sit there, see everybody talk, and do nothing for the group. I tried to follow their conversation and see if I can understand the solution to the problems they figured out…but it didn’t work…I thought maybe it was because I kept thinking about the content that would be shown in the quiz instead of focusing on the class. After the class, I went to Brooklyn Bridge to see the night piece of Manhattan with my friends. However, I could not stop thinking about the class. And it annoyed me so much that I didn’t even have to mood to enjoy the great view there…
Sigh…
I have to go now…to work on my textbook!
