Ever have one of those days?

It feels to me that today either my brain cells are dead or they are misfiring, or both; I mean, why chose between the two.  I was completely lost in class today and it feels as though I am in a fog.  Even typing this now things just feel a bit off.  Carsten was ill yesterday so maybe his bug jumped ship and onto mine.  Whatever it is, I don't much care for it!!  Thankfully I have Hart-to-Hart to look forward to.
