Lyrics:

Build a wall of books
Between us in our bed
Repeat, repeat the words
That I know we both said
Relax into the need
We get so comfortable
Remember when I was
So strange and likable
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 how sweet and unexplainable
Nothing like this person, unlovable
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
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
