Even worse, one of you goes out and returns to find that the other has had a sneaky evening alone with the box set. This is a new and wounding kind of infidelity. How could he/she? Your chances of getting back in sync are nil, now your spouse knows that the blonde aide was having an affair with the minister in hospital who hasn’t really had a heart attack after all. Suddenly, your relationship is in crisis. There are issues of trust. One feels resentful, cheated of a shared pleasure. The other is longing to find out what happens on the next disc and hates the fact that a dozy partner makes him/her feel bad about indulging this addiction. I know one woman who sought a divorce after the husband started a box set of House without her. Himself, meanwhile, has never forgiven me for watching the final two episodes of The Killing while he was away. He’d rather I’d spent the night with Johnny Depp.
