Glorious glittery firework of a human being whose presence in my life has fortunately lasted much longer than most pyrotechnics manage. The only person in the world who has voluntarily shared a house with me on repeated occasions, and we've hardly killed each other at all.

It would be both slightly misleading and saddening to refer to them as the Tara to my Willow, so I'll stick with calling them the Nanny Ogg to my Granny Weatherwax -- I'm not sure there's any higher compliment in the world than that.
