Is it weird that I noticed that my professor re-died her hair? Last class, I noticed there was some grey at the roots and some grey strands throughout, which I had never noticed before. Today, the color was richer than it had been the previous class. And I could tell where the grey strands had been because they were even brighter than the rest of the hair.

Re-reading this: yes, it's weird and kind of creepy that I noticed all that. The thing is, I have to focus intently on the professor's face in order to stay focused and concentrate. The hair is right next to the face. So, when I start spacing out (despite my best effort not to), the hair next to the face is the first thing I see.
