I don't know if you remember, but your beautiful un-cousin was born deprived of what some would call an "adequate" sense of balance. Many were the splicing mishap she suffered during apparation, but never did she fear for she was always reminded that there was always her beloved broom, just sitting there, always ready to take one for the team. Oh, sure, it wasn't always an easy ride. Sure, she may have taken a while to figure out how to ride on a broom in something other than upside-down position. And sure, Big Ben may be missing a hand (in her defense, what kind of a moron puts up a giant, heaping clock in the middle of a skyline, anyway? But I digress.) The point of the matter is, a broom provided to her, your cousin, a safer, gentler traveling alternative as opposed to apparating herself inside walls and the occasional vase.
But you have taken that from her, dear cousin. You have taken that from her and henceforth you will have to Pay.
So oh, I will be there.
And you can't hide it forever!
P.S. So what should I bring for the blushing couple? His and Her towels? A nice engraved dinnerware set with your flourishing initials intertwined? Matching jammies is always an extremely tasteful housewarming gift, I find.
