Oh come now, Eric! Everything moves in conic sections? How
poetic. One can imagine Eric and his wife circling each other in
the kitchen. Do they ever kiss? Wait! They're coming close,
closer, closer, but OH, her mometum caused her to follow that
darn curve that she is bound to follow.
Is this silly? You bet!
