Husband and I sat down for a quick dinner of fishcakes with his parents last night. MIL suddenly leapt up and said "Oh no! We need fish-knives!"
She then berated my husband for his lack of etiquette in laying the table with ordinary knives.
The thing is, it was quite tricky to eat fish-cakes with fish-knives. I struggled on, but spotted MIL giving up and using her fork!
