An expectation can become unfair without ever being spoken aloud.

Unspoken expectations grow because nobody has to defend them. A pattern settles in, one person keeps doing the thing, and over years it hardens into an assumption that would sound unreasonable if anybody put it in a sentence. Silence protects it from the test that speaking would apply. That is why the most lopsided arrangements are often the ones never discussed.

Take something you assume about a person close to you and say it aloud as a request. If it sounds unreasonable when spoken, it was unreasonable when silent. Let them answer as though it were being asked for the first time.
