What? Why am I here as a Guest? What's happened? I was sitting in my office here at home, doing a spate of matrix algebra as is my wont of an evening, when I "came all funny" as my grandma used to say. My potato chips are cold, my coffee is warm and I feel like I was possessed by an alien intelligence or something.

I'd go to bed except that I have to go to work. Geez, it's Wednesday already!
