Just Sitting Around at Home

I was just sitting around, twiddling my thumbs (didn't know I could twiddle, did you?) and decided to watch the movie 'An Affair to Remember,' with Cary Grant and Deborah Kerr - you know, the one where they meet on the ship, fall in love, then promise to meet in six months time at the top of The Empire State Building in New York, only she is staring up at the top of the building while she's on her way to meet him, and there's the hint that she's hit by a car... Long story short, she doesn't show up because she can't... then, much later, the two meet again by chance, and it's Christmas, and his grandmother left a shawl for her when the grandmother died... To make a long story short, he finds her in her apartment, stretched out on the couch with a blanket over her legs, no wheelchair in sight, and he has to figure out what's happened to her... And all the time, I'm sitting there, watching this movie, seeing them go through the motions of their first meeting in ... what? A year?... and all I can think is that she's there, on the couch, there's no wheelchair, and she can't walk... What the heck does she do if she has to use the bathroom? Is she supposed to crawl there?

Isn't it weird what you think while watching the climax scene of a movie?
