I figured it out.
I figured while watching you out in the rain.
From the obscured viewpoint of the warmth and safety of my seat, clashing against the temperature at odds with the outside, in  foggy condensation at my window.
Watching you,
Cold and wild
Wet and Savage.
You. You are the reason, I think.
I think.
For the expression,
"Hasn't enough sense to come out of the rain"
