In the National Gallery this afternoon:
Oyster: What does "National" mean in this case?
Mama (*trips over own brain somewhat*): Well ... it's the national gallery, which means ... well, it means it's for the whole country. "Nation" basically means "country", and this is the National Gallery because it's ... not a specialised one, not just for one sort of art or one place ... hmm ... I mean, it's like, the most important one in the whole country.

Five minutes later:
Oyster: So, me and Fiachra are your gallery children.
Mama: My gallery children?

And then I worked it out, and assured him that YES, he and Fiachra are my most important children in the whole country, if not the world.

Then he asked what a gallery was, so I explained that.

And then Oisín and I held hands, and I pushed the buggy containing Fiachra, and we danced out into the snow.
