A man sitting in a small living room with his wife and live-in mother-in-law, ‘casually’ mentions a new super-large-screen TV, available from Currys.

When he says the TV would need a bigger room, his wife reminds him her mother lives in the ‘big’ room.

Prepared, he produces an old cassette player and presses ‘play’. Sad, affecting music provides the background for a ‘worried’ speech about how such a big room is bad for the old lady’s health.

It’s partly ingenious, partly clumsy. But mostly a manipulative attempt to get the huge new TV into the big room and the old lady into the tiny ‘Box Room’. His wife totally sees though him.
