Dc today (both of them, aged 7 &9)kept insisting that the word 'advent' means countdown. A teacher told them so apparently. Annoyingly, ds1 told me proudly 2 years ago that he was the only one in assembly to know the real meaning, but he too now insists it means countdown.
Ds2 insists on saying 'could/would etc of', with the 'of' firmly pronounced. I try to encourage the understated 'uv' sound (not come across it in his writing ) but he says Dad says 'of' is fine - we are divorcing. I know ex is a ridiculous inverted snob of the highest degree, but ffs. I teach countless kids who write this way, and I find it impossible to let it pass without comment.
I know in both cases that the more I say, the more they insist, so why do I do it? Doesn't help that they are both currently of the mind that Dad is right and I am wrong, and that I am the world's worst/strictest mum...
