Not every room requires your participation.
Some rooms are organized around ridicule. Some depend on your defensiveness. Some only feel powerful while you are standing there trying to explain yourself.

Disengagement is not always avoidance. Sometimes it is the moment you stop offering your presence to a space that cannot hold it with care.
Not every room deserves your explanation.
Some rooms are simply meant to be outgrown.
