Whoever decided to schedule four exams in the week before Christmas obviously isn’t a mother. Three down, one to go tomorrow. I am allowing myself an evening off on Friday before transforming myself, Clark Kent-like, into Wonderwoman (yes, yes, I am mixing my superheroes, but if you had had a week like mine, you would be too). On Saturday morning I will be ready to leap tall buildings with a single bound and conjure up a magical Christmas experience before my guests arrive. Well that’s the theory anyway. When I wave everyone a fond farewell a few days later, I get back in the figurative phone-box and put the glasses back on ready to study for the next round of exams. Happy days.
