Privacy

The saying urges goodwill toward nearby people while preserving sensible personal limits. Its older “thy” gives the traditional wording an archaic tone. Kindness, cooperation, and affection do not require surrendering boundaries that protect one’s home, privacy, property, or independence.

Someone who listens in on talk not meant for them may hear criticism rather than praise. The saying warns that overheard conversation can be painful when it reveals unflattering private opinions.

The proverb presents the home as a place where its occupant can expect privacy and decide what happens within it. The castle image conveys security and independence.

A pair may enjoy one another’s company most when left alone. Adding a third person can change the encounter so much that it no longer feels companionable.
