The Wall

I don't know you anymore I can't figure you out. You have closed yourself off to me. You have built the wall and you won't let me in. Why? That's all that I want to know. We used to be able to love each other, but you keep pushing me away. Why? I'm standing at the wall begging for you to tear it down, but you won't. Why? What did I ever do? All I wanted was to love you, but I can't. Please just let me know. Why?
