All persons are like gurus to us.

According to Ramana Maharshi, the sage of South India, answering a visitor discouraged by the evil in the world, everyone can be a guru, a spiritual teacher, for us: the good person shows us the way through their goodness, and the one who acts badly teaches us, by their example, what is better not to do. Today, before someone who irritates or hurts you, ask yourself without judging them: “What are you teaching me?”
