You get the air out of my lungs whenever you need it
And you take the blade right out of my heart
Just so you can watch me bleed
And I still don't know why, why I love you so much
Go on, fill your cup with my blood. Fill it till it runneth over.
Then sip on it to your heart's content. That is, if you can find it in your heart to be content.
Knowing you, though, I'm certain you're going to bleed me dry before you do.
