The truth told at the wrong moment just becomes a fight. Wait until they can actually hear it.

Accuracy is not the only requirement for something to land. A true thing said to someone who is exhausted, embarrassed or already defending themselves gets processed as an attack, and then the conversation is about delivery instead of content. Being right at the wrong time achieves nothing except being right.

If you have something real to say, choose the moment as carefully as the words. Not in front of others, not at the end of a bad day, not in the middle of the thing itself. Say you want to talk and let them pick when. The truth keeps.
