Existentialism on Prom Night

When the sun came up,
We were sleeping in,
Sunk inside our blankets,
Sprawled across the bed,
And we were dreaming,

There are moments when,
When I know it and
The world revolves around us,
And we're keeping it,
Keep it all going,
This delicate balance,
Vulnerable all knowing,
Sing like you think no one's listening,

You would kill for this,
Just a little bit,
Just a little bit,
You would, kill for this

Sing like you think no one's listening,
You would kill for this,
Just a little bit,
Just a little bit,
You would, you would...

Sing me something soft,
Sad and delicate,
Or loud and out of key,
Sing me anything,
we're glad for what we've got,
Done with what we've lost
Our whole lives laid out right in front of us,

Sing like you think no one's listening,
You would kill for this,
Just a little bit,
Just a little bit,
You would,
Sing like you think no one's listening,
You would kill for this,
Just a little bit,
Just a little bit,
You would, you would....
Sing me something soft,
Sad and delicate,
Or loud and out of key,
Sing me anything.
