Fine at the Departures Curb

Streetlights clicking off one by one,
I said you love it there, I said have fun.
I'm fine, I'm fine, dropping you at the plain.
I'm fine, I'm fine, I'm dropping you at the plain.
Smiling at the curb like it's nothing, like it's no pain.
I'll wave you through the door and keep my smile dry,
Then the sun comes up slow and I start to cry.
The speaker calls the flights in a voice that's flat; you hug me quick and say,
