On another note, my father, on the verge of carking it for the past 15 years or so, has been through a fair few doctors in his time (I'm talking GPs not Timelords). Of that vast throng, one was called Doctor Watson; another Doctor Pepper (honestly). Now he just needs to seek out a Doctor Who for the full complement of famous doctors. Let's hope he lives long enough to find one. Speaking of which, my mother's buggered off on holiday without him again. Along with the other sisters, I've been asked to ring him regularly to check he's not dead. Poor old dad. We do tease him so. But when you've been banging on about how ill you are and how you don't think you've got long left. For 15 bloody years. You can't expect to get away without a bit of sarky comment from your exasperated daughters.
