Everybody uses pop culture as a shorthand.

I watched a lot of YouTube videos of cute geeky girls playing '80s cover tunes on ukuleles. Technically, this wasn't part of my research, but I had a serious cute-geeky-girls-playing-ukuleles fetish that I can neither explain nor defend.

"Lights," I said softly. This had become my favorite word over the past week. In my mind, it had become synonymous with freedom.

One person can keep a secret, but not two.

As we continued to talk, going through the motions of getting to know each other, I realized that we already did know each other, as well as any two people could. We’d known each other for years, in the most intimate way possible. We’d connected on a purely mental level. I understood her, trusted her, and loved her as a dear friend. None of that had changed, or could be changed by anything as inconsequential as her gender, or skin color, or sexual orientation.

If I was feeling depressed or frustrated about my lot in life, all I had to do was tap the Player One button, and my worries would instantly slip away as my mind focused itself on the relentless pixelated onslaught on the screen in front of me. There, inside the game's two-dimensional universe, life was simple: It's just you against the machine. Move with your left hand, shoot with your right, and try to stay alive as long as possible.

I've retroactively made all that wasted time rotting my brain into research. It makes me a hypocrite when I try to tell my own daughter, "I don't know, I think we've played a little too much Mario."
