When my sister and I talk, we don't really talk – at least, not in the usual way.
Instead, we communicate in in movie dialogue, lines lifted from movies of the 80s and 90s that feel etched directly into our bones.
If I call her and she answers with 'Hello, Dyan,' in a broad New York accent, I don't say 'Hi, how are you,' because I know my line is, 'Take a look at these swatches.'
If she signs off with, 'I'll see ya,' in a soft, boyish American drawl, my reply is always: 'Not if I see you first.' It's like a call-and-response game we just can't quit.
I'm sure it's massively annoying for other people. Imagine we're out shopping: we park the car and she lags behind. I yell, 'You didn't get out of the cockadoodie car!' She scrunches up her face and wails, 'Oh, I love you, Paul. Oh, I love you!'
Whole scenes from When Harry Met Sally regularly spill out of us; our most uncanny impressions come from The Princess Bride ('Inconceivable!').
And my favourite retort to any favour she asks is: 'Elise, if I give you any more collagen your lips are gonna look like they got stuck in a pool drain.'
