She was my once in a lifetime. Happy ending come true. Oh I guess I should have told her. I thought she knew. She said I took her for granted. That's the last thing I would do. Whoa I'll never understand it. I thought she knew. I thought she knew. I thought she knew. My world revolved around her. My love light burned for her alone. But she couldn't see the flame. Only myself to blame. I should have known. I should have known. A heart full of words left unspoken. Now that we're through. I'd sell my soul to have this silence broken. Oh I thought she knew. I thought she knew. I thought she knew. My world revolved around her. My love light burned for her alone. But she couldn't see the flame. Only myself to blame. I should have known. I should have known. She was my once in a lifetime. Happy ending come true. Whoa I guess I should have told her. But I thought she knew. (I thought she knew). I thought she knew. (I thought she knew). I thought she knew. (I thought she knew). Oooooooo. Oh I thought that she knew. Yeah ooooooo
