Input: Text: this happened when looper first released, so spoilers if you haven't seen it as it involves a scene from it.

my fiancée was working as a cleaner, which necessitated some early starts and i have a kid who needed to be in bed before we could go out, so by the time we normally made it to the cinema it was for a 9pm showing.

this time, maybe about an hour in the lovely lady of my life fell asleep, just in time for the scene in which the antagonists future self is bumping off the young versions of the future crime kingpin.

the cinema is silent as he approaches the house, the tension is palpable... he knocks at the door and a small child answers... my girlfriend snoozes entirely unaware.

he brings the gun up and a single gunshot rings out.

with this my future-fiancée leaps up out of her chair as though it's her that's been shot and i laugh. 

i laugh loud, it rolls across the shocked audience and as one they turn in their chairs to stare at me, the feeling of disapproval coming off them in waves.

that day i fucked up by making hundreds of people think i found child murder hilarious.

god knows how they recognised me, but afterwards there were plenty of unveiled glares and audible mutters as people passed me after we'd left.
