The person who includes you in the decision has offered more than a warm explanation afterward.

Being told kindly why something was decided is not the same as being asked. One treats you as an audience, the other as a participant. A good explanation after the fact can still be a courtesy, but it arrives when nothing can change, and part of you knows that. Inclusion costs the decider something real: time, and the risk of hearing a view they did not want.

Look at the decisions you make that land on other people, and pick one where you could ask before you settle it. Ask early enough that the answer could still move you. And when someone does that for you, notice it.
