The husband has a right to keep his private space as he sees fit. His wife's unsolicited intrusions and reorganizations are a clear violation of his personal boundaries. Replacing lost items is a reasonable response to her actions, not an act of impatience.
The husband's passive-aggressive behavior of replacing items instead of communicating directly with his wife exacerbates the situation. His claim of respecting her kitchen rules while disregarding her feelings about clutter in their shared home is hypocritical. He provokes this situation by his passive-aggressive actions.
While the husband has a right to his private space, his method of dealing with the issue—secretly replacing items—is childish and avoids direct communication. The wife's repeated entry into his room and displacement of his belongings are clear violations of his boundaries. However, his passive-aggressive response is not the way a mature person handles it. This is an example of 'Don't be a dick'.
