Empty box

I'm just an empty box
What do you want to fill me with?
'cause I'm just an empty box
There's room for anything to make you pleased
Right now I'm an empty box
Put your love and pain into me
And after I put on the locks
There'll be nothing left to see

I'm just an empty box
Please give me all that you don't need
'cause if I'm not filled by noon
I'll start to deform and bleed
I'm just a box for your needs
Fill me up, tie me up, put me away
And when you'll need an empty box
You can take me back into the light of the day
