People can learn to endure the times where no sound from others around may reach them. You don’t need to speak loud enough to make someone listen, interjections don’t help. Limited noise can get you places, even among friends who share the same locks a life holds on to. You can see so much, under and within the noise.
Never be afraid to break that silence, however. That sudden shift in space-time in the moment is mighty, even against yourself.
Silence is key.
