don't you know where you live?

This is the unofficial name of a small estate in Chapelizod, Dublin. It is a large concrete block surrounded by flowers, which are most attractively maintained by locals. The only problem is that almost facing it is this:

the official Dublin City Council name plate. It doesn't take much to see that the two are contradictory. I don't understand such imprecision. Doesn't it bother people that they might not know the name of their street or grove? St Laurence Rd is often 'corrected' to St Laurence's Rd, perhaps because people have an overwhelming desire to identify something with somebody, just as the corner shop used to be Martin Smith's or just Smith's. Now it's more likely to be Tesco, but not quite so local, and nobody wants to call it that: it's 'Tesco's', probably written 'Tescos'.
