Sunshine Proves All Wrongness

If I wrote you a letter would you send it right back?
If it made you feel better would you pull in the slack?
If I wrote you a smile
keep it for a while, dear,
I'm finished with it anyway.

If the sun would shine brighter then I'm sleep less okay
There's a bend in the wire, I can't ring you today.
If I saw you in light
then you could see i might, dear,
use a windowshade right away.
