Leaving it Behind

I'm starting to wonder if my psychology teacher isn't a bit mental. It's not that she isn't mentally sound, I just don't know if she's capable of acting "normal." I put normal in quotes because there can be no complete, concrete definition of normal...but still. I don't always understand what's going through this woman's head. Actually, I don't understand what's going through her head most of the time. That should make class a bit more interesting.
