Don't smother each other. No one can grow in shade.

Buscaglia’s line uses a plant-growth metaphor to argue that love and intimacy become harmful when they turn into overprotection, control, or constant proximity. “Smothering” suggests affection that deprives the other person of air—space to think, choose, fail, and develop an independent identity. The “shade” image implies that one person’s needs, fears, or dominance can block the light another requires to flourish. The quote therefore reframes healthy relationships as those that balance closeness with autonomy: support without possession, care without surveillance. It also serves as a warning against dependency, urging partners, friends, and families to cultivate conditions where each person can continue growing.
