You just do everything to my heart. I can't help it. Some nights I wake up in the middle of the night And I realize I don't know if you'll stick around in my life And it pounds and it won't stop Even when I measure my breaths. It likes to stall when you're around Or even when I think about you too much, Like an old car that's been left out in the rain and won't start fully. It chugs along and turns over rough, And it almost hurts sometimes. My heart Does whatever it wants to. Sometimes I could swear it wants Out of me And it tries to pry open my ribs and go off somewhere to find... You, I guess. It doubles speed when you look at me, And I read somewhere about a scientific theory That every heart has a set number of beats Before it wears out, And I wonder if you really are killing me, And I decide I'm okay with it.
