Tip toe, down the hallway
Kiss your hair as you stay sleeping
And I don't have the time
To stay and argue with you
My flight's leaving, say goodbye

Sleep, oh-oh-oh, sleep
I'll call you when I can
I'm busy like I always am

I'm waiting by my phone
I know you're busy
I got this heart-shaped hole
And I know you don't have the time
But I'm forgetting what you sound like
What I wouldn't give to argue now

Sleep, oh-oh-oh, sleep
I'll call you when I can
I'm busy like I always am

You used to say I love you
When you said goodbye
You used to say I love you
When you said goodbye

Sleep, oh-oh-oh, sleep
I'll call you when I can
I'm busy like I always am

Sleep, oh-oh-oh, sleep
I'll call you when I can
I'm busy like I always am
