Every system has a natural frequency where energy input creates maximum effect. Couples have one too. Force the wrong rhythm and the relationship resists; find the right one and small efforts amplify.
A pendulum swings past center before it settles. After a fight, couples overcorrect, swing back, then overcorrect less—until they finally find equilibrium. Recognizing the oscillation is the work.
The human eye sees about 200° horizontally—nowhere near the full 360°. Visibility into a partner's life works the same way: limited by design, healthier with explicit borders.
Electrons repel when forced too close—an electrostatic response to invasion of space. Couples do the same thing, and the way the system releases that pressure decides whether the bond holds.
