\nYou can give type O blood to blood groups A and AB. You can give type A blood to type AB. You cannot give type AB to anybody except AB.\n<\/p>\n
\nButter knives in our kitchen work the same way. You can use a knife that has previously been used for Adrian’s dairy-free margarine on both butter and Ingrid’s liver pâté. A knife that has been in contact with butter can be used for liver pâté but not for margarine. A knife with liver pâté on it can not be used for anything else.\n<\/p>\n
\nThe complication is that remains of butter and margarine are almost impossible to tell apart. So whenever Adrian wants a sandwich, we have to get a new knife for him. This is why there is an almost-constant shortage of butter knives in our kitchen even though we have half a dozen.\n<\/p>\n
\n(On weekend mornings there is also orange marmalade to be taken into account but that luckily does not look like anything else and can be eaten by everybody.)<\/p>\n","protected":false},"excerpt":{"rendered":"
