Ella was preparing to go to a dinner party a couple of nights ago and I heard her great-grandmother was going to be there.
Me - Do you know how old your great-grandmother is, Ella?
Ella - No?
Me - She's 93!
Ella - [Opening eyes and mouth wide in an expression of sheer astonishment] Wow! That's just too old! She should be died.
It was futile to try control my laughter. I did only just manage to say to her that she should never, ever tell her great-grandmother what she'd just told me.
