Build a wall of books between us in our bed. Repeat, repeat, the words I know we both said. Relax into the need, we get so comfortable. Remember when I was so strange and likeable? I just want back in your head. I just want back in your head. I'm not unfaithful, but I'll stray. When I get a little scared, When I get a little scared, When I get a little, When I jerk away from holding hands with you, I know these habits hurt important parts of you. Remember when I was sweet and unexplainable? Nothing like this person, un-loveable. I just want back in your head. I just want back in your head. I'm not unfaithful, but I'll stray. When I get a little scared, When I get a little scared, When I get a little scared, When I get a little, Run, run, run, run. Run, run, run, run. I just want back in your head. I just want back in your head. I'm not unfaithful, but I'll stray. I'm not unfaithful, but I'll stray. I'm not unfaithful, but I'll stray. I'm not unfaithful, but I'll stray.
