As advised, I have now screwed our new enamel house number onto our letter box, where it can clearly be seen by anyone who might wish to find us (provided they know our number).
Having previously been reached by our name, and that of our tiny hamlet, we now have both a house number and a street address that should (we are advised) be used at all times.
However, I did notice that on the letter that accompanied the delivery of our new number plaque, that the mayor's office failed to use their own new address, and where the letter had been addressed to us on the envelope, they didn't use our new one either.
I have owned this small house for about 45 of my 50 years residence in France, but I have obviously failed to notice one very important thing. Being number 268, I had failed to notice the other 265 homes further up the road in our tiny 3 house hamlet. Where can they be?
Lord, give me strength.
