We've got a name and a number, the name came first and was there when we bought the house, - it is a German name, and no one can pronounce it properly, and I always have to spell it out. So I was quite pleased when we were told we all had to have a number, and I no longer bother with the name.
Some people in the village don't display their numbers though, preferring to stick to their poncy house names and assume anyone who is worth bothering with will be happy to work out that Bide-a-Wee and No.70 are one and the same.
