Ah. [1]#Science - it was always one of my favorite subjects.
   Silly teacher didn't understand: I left questions unanswered
   because I didn't have the answers. I was eager to discuss
   because I wanted to be sure I understood it. Wasn't my fault,
   teacher.* If I didn't 'get it', you didn't address it :P I was
   supposed to guess for grades?* Meh.* If I didn't know it, I
   didn't know it.[2]science-left-questions-unanswered
