Have you ever been talking with a group of people, and someone in the group starts spouting off a bunch of facts that aren'ttttt exactly true, and you feel compelled to set them straight? Or they start wildly embellishing a story, and you feel the urge to offer the, you know...TRUE version? Or maybe you're arguing with a friend, and they really messed up and dropped the friendship ball, and are getting defensive and combative when you call them out on it.
I don't know about you, but in situations like these, my hunger to be right is POWERFUL. They're wrong, and the world needs to know.
The more I learn about life, the more I realize how inferior being right is to being KIND. Kindness trumps all. However, it should be noted: Kindness doesn't necessarily mean nodding agreeably when someone is spewing inaccuracies that could be harmful/hurtful to others/lead them astray in a significant way. But if your friend is regaling others with her tale of being up front at the Beyonce concert (when in reality she was sharing binoculars with you in the nosebleeds), what's the big deal? Does it hurt anyone? Why embarrass her in front of others, just to set the record straight?
What's more important is to focus on what's causing that person to act the way they're acting, and say the things they're saying. Why do they feel the need to bolster their credibility/image/etc? Are they feeling undervalued and depressed? Are they bumming about a rejection, in their personal or professional life? Are they insecure about their worth? Or in the example of them being a less than ideal friend, what led them to make that mistake?
It can be really tough, but oh-so-more rewarding to check your ego and anger, and dig a little deeper. Dissolve your anger with kindness, compassion, and empathy. At least try to understand why they did what they did. If you do, it's actually a win win: It encourages a more peaceful and effective solution, which discourages repeat occurrences. If you can tease out the root of the problem, you can be the friend they need, and likely prevent it from re-manifesting (as suppressed, unresolved issues often do).
