The floorboards ached like the countless bruises you trace with your lips.
They sound a lot like the process of falling in love with you:

I'm not sure where they came from or when it happened.
One night in the shower, they just lined my skin.
I don't know what exactly caused them,
and I didn't even notice they were there until someone pointed them out to me.

They cover my limbs, but on the upside,
they contrast wonderfully with my paleness.
