“You know a relationship has deteriorated past the point of salvage when one person detests another’s gestures.” Josephine Humphreys, an American novelist.
Wow. That would sure be simple. There are, I believe, gestures that annoy married couples with half a century of solid viability.
How about the gestures of continuous nighttime snoring in three octaves? How about the gestures of snapping down on those chips with enhanced clarity?
Past the point of salvage gestures? Perhaps emptying the entire joint bank account and moving to Tahiti? That might not be salvageable.
