Just watch any husband arguing with his wife about something insignificant; listen to what they say and watch how their residual emotions manifest when the fight is over. It's so formulaic and unsurprising that you woudn't dare re-create it in a movie. All the critics would mock it. They'd all say the screenwriter was a hack who didn't even try. This is why movies have less value than we like to pretend -- movies can't show reality, because honest depictions of reality offend intelligent people.
The reality I got to see was not "movie reality." The reality I saw was just reality, without quotes. You want to know what I really learned? I learned that most people don't consider time alone as part of their life. Being alone is just a stretch of isolation they want to escape from. I saw a lot of wine-drinking, a lot of compulsive drug use, a lot of sleeping with the television on. It was less festive than I anticipated. My view had always been that I was my most alive when I was totally alone, because that was the only time I could live without fear of how my actions were being scrutinized and interpreted. What I came to realize is that people need their actions to be scrutinized and interpreted in order to feel like what they're doing matters. Singular, solitary moments are like television pilots that never get aired. They don't count.
