Box in a Box

She's a box in a box
She's underneath the floor
She's a curtain that went down
She's shut behind the door
Don't ask when it was better
She'll say that it's never
She's clever like a fox
She's not one to deny it
But it never mattered half as much
As her skill for staying quiet
Don't ask when it was different
She'll say that it isn't
Some days time flies
Sometimes days go by
She's a lock that's been locked
The keys are in her pocket
She could walk right out the door
But she refuses to unlock it
Don't ask when it will end
She'll say it's hard to tell
She doesn't know herself that well
