The toothpaste lands in the sink when you spit. You turn off the water and move to walk away. Then you remember. You walk back to the sink and, with one lonely finger under the tap, you wipe away the dot left behind. You stare at the spot that might never have been real. You shake your head. You wonder why it matters anyway.
You walk into the bedroom where you have traded one set of keys for another. You think back to the spot. You never deserved that first set of keys anyway. The little blue dot. You walk back into the bathroom. You half wish it was still there. It's easier to wipe something clean when you can still see it clearly. You consider brushing again, maybe try to recreate the spot. You shake your head again. You tell yourself to let it go. It's just a spot. it's just a tiny, little spot. Easily removed, easily replaced. At least, that's what you tell yourself.
You go to sleep, in the morning there will be new brushes and teeth and spots to wipe clean.
