“When your sparring partner scratches or head-butts you, you don’t then make a show of it, or protest, or view him with suspicion or as plotting against you. And yet you keep an eye on him, not as an enemy or with suspicion, but with a healthy avoidance. You should act this way with all things in life. We should give a pass to many things with our fellow trainees. For, as I’ve said, it’s possible to avoid without suspicion or hate.”

Marcus Aurelius, Meditations, via The Daily Stoic (Page 128)
