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!
