Mum likes nothing more than to turn the television volume up to the highest setting and put the subtitles on at the same time. She says the actors mumble. I say she’s going deaf.

When SS-GB (BBC One, Sundays) premiered on Sunday night, I decided to take a stand. The show started, Mum reached for the subtitles button. I grabbed the remote from her. “Don’t you dare!”

I said. “Just for once – for once – I’d like to watch a TV show without feeling like I’m reading the script at the same time.”

Triumphant, I stuffed the remote down the side of the settee and settled back to enjoy the show.
