Lyrics to Center of Gravity

In crowded bars, at subway carsWhenever you are next to me,
center of gravity,
can't feel both feet on the groundWalking home after dark, past the softball parkIt's clear to me, according to a rule I learned one day in school
Basic geometry: two halves of a circle, you and meIt's a familial song we've known so longYour clever cuts into me
as long as you're next to me
I can't feel both feet on the ground
