Teaching rots your brain.

Yesterday, after running around frantically trying to prepare materials for class, I rushed up to the door to my office, stopping to set all of my stuff down so that I could search through my purse and find the key.

I couldn't find it, and panicked when I realized I had left it in the office.

I tried the knob and sighed with relief when it turned.

Then, I realized, I don't have a key to the office.  There is no key to the office.  They don't ever lock the office.  

I am officially losing my mind.
