Not too long ago, M1 openly complained that M2 has been very soft and called her a tofu; M2 took to heart her association with the food type.
We went out for dinner on one occasion and I happened to order tofu and scooped some for M2 to eat but she declined and said,”Mummy, I don’t eat my kind.”
“Huh?”
“She’s a tofu and she doesn’t eat her kind,” M1 explained.
Ahhh… What a clever new excuse to avoid food that one does not like.
