For some reason, hooking up trailers is in my head because I was hooking up the one yesterday and something wasn't quite right. And if it's dark, you can't see. You can feel and things like that, but you turn, you get your flashlight out and, oh, you can see. That's the problem. The thing is stuck in the wrong place. It helps us to know what's going on and also creates openness. Things hide in the dark. Like children, when you're afraid of something at night, what do you do? You turn the light on and then you can.
