“There’s a bluebird in my heart
That wants to get out but I’m too clever
I only let him out at night sometimes
When everybody sleeps

I say: “I know that you’re there
Don’t be so sad, ” that’s what I said
Then I put him back but he’s always singing
I don’t let him die and we sleep together
Like that with our secret pact…”
– Bluebird by Charles Bukowski
