This one has NOTHING to do with ballet.
I spent Saturday afternoon at the Warner Brothers studios where Harry Potter was filmed. It's amazing. Should you find yourself in London and enjoy Harry Potter, be sure to go.
Unfortunately, by the end of my tour I felt that familiar ache behind my eyes that signals a fever. And sure enough, my temp was rather elevated. Rather than the nice evening I had planned I drove to my hotel early and went to bed.
Since then I've felt better and better. Spent yesterday wandering around central London playing tourist with no issues. I may substitute Claritin for the Zyrtec I've taken since Friday and see if that gives me the allergy relief I need without the negative side-effects. OTOH, I'm keeping the Zyrtec handy in case I need it.
