Mummy? Said L this morning over the rice krispies. What's a gnome?
It's a sort of fairy.
Oh. And what's a pixie?
Erm, that's a sort of fairy too.
Well how do you know the difference? And is the tooth fairy a pixie or a gnome, or something else?
Of course, as any ful kno - and I realised, while pondering once she'd been packed off to school - a gnome has a beard and a pixie doesn't. And neither of them has wings, which a real fairy (and the tooth fairy, obviously) does.
But what about kelpies, or leprechauns, or sprites? Or elves (I think they probably have beards too), hobgoblins and imps?
And why don't they cover this sort of thing in the parenting manuals?
