Losing the plot

I was in a cinema, watching a film. The man in the seat in front of me was very tall and blocking my view so, as there were lots of empty seats, I moved a few rows forward. The film was not very interesting, the plot was derivative and I could not keep my attention on it. A woman got up to leave and seemed to snag my earphones as she got up. I let the cord play out, knowing it would bring her to an abrupt stop. She returned with an extension lead with an absurd number of electrical plugs attached to it in a tangled mess and handed it to me. I left, bored with the film, and wandered through town. I felt a kind of guilt at not staying to the end and returned but it seemed to have ended and something else that I did not understand was happening on the stage.
