I Am a Heart

I am a heart that's hard to pin You are an arrow sticking in I pull you out and put you down With all the others, scattered 'round You won't give up that easy though You turn to roots, a tree you grow Your ivy walls can't keep me in I am a heart that's hard to pin I am a heart that's hard to pin You dig a hole and I fall in But I'm still beating underground Down here you think I won't be found I won't give up that easy though My heart's the seed, a tree will grow My bark will be a thicker skin I am a heart that's hard to pin Oh, you can't win Mine is just a little hard Hard to pin No, you can't win Mine is just a little hard Hard to pin I am a heart that's hard to pin You are an arrow sticking in To pin me down's the hardest part I am a heart
