Constant Headache

I could hear you coming, so I hid by the couch
You were talking so loudly, I don't know what about
But you were drunker than high school
Self-conscious and sweet
I never ever felt so cool disguised in your sheets
But I'm a constant headache, a tooth out of line
They try to make you regret it
You tell 'em, no, not this time
It's just a constant headache, a dead pet device
You hang me up unfinished
With the better part of me no longer mine
And then you finally found me, pretending to sleep
You said such nice things about me, I felt guilty and cheap
You took two steps to the kitchen and just stared at the sink
I couldn't hold back a smile, I still wish I could have seen
You having sex in the morning, your love was foreign to me
It made me think maybe human's not such a bad thing to be
But I just laid there in protest, entirely fucked
It's such a stubborn reminder one perfect night's not enough
It's just a constant headache, a tooth out of line
They try to make you regret it
You tell 'em, no, not this time
It's just a constant headache, a dead pet device
You hang me up unfinished
With the better part of me no longer mine
