You can decline the slight

A coworker walks past your desk without a word. The group chat plans lunch and your name isn't on it. A client copies everyone but you on the email. Small wrongs, the kind too petty to raise and too sharp to ignore, and each one arrives asking you to take it personally. Most of the day's injuries are this size.

Here a practice lands. Marcus: "It is in our power to have no opinion about a thing, and not to be disturbed in our soul; for things themselves have no natural power to form our judgments" (Meditations 6.52, Long). The silent walk-by is a fact. He's snubbing me is a verdict you reached and could refuse to reach. Maybe he didn't see you. Maybe he's drowning. Maybe he is being cold — and even then, his coldness is a thing happening over there, not an order you're obliged to obey by feeling crushed.

Try it the next time a small slight lands: hold the bare event, and just decline to file the case. No opinion. The nurse mid-shift, the driver cut off in traffic, the cashier ignored by a rude customer — each gets handed these all day, and each can let most of them pass through unsigned.
