Can’t Remember Where The Argument Stemmed From

(My parents, both in their fifties, are bickering over dinner one day about what part of the broccoli mum prefers. This goes on for a while.)

Mum: “No, I like broccoli STEMS, but not the flowers.”

Dad: “Huh… weird. Okay.”

Me: “…and you’ve been married how long?”

Mum: “I’ve told him before; he’s just forgotten.” *returns to eating*

Dad: “…is this the part where I apologise?”

Mum: “Hmm?”

Dad: “Is this where I apologise?”

Mum: “Oh, no. I can’t actually remember what we were talking about.”
