Crisis apparitions are smart spirits that tend to appear before a critical moment. As a messenger, they like to impart important information. Just like these apparitions, something tells us that when you've heard some news, you can't help but spread the word. Some may consider this gossip, but we like to think it's knowledge production.
You might have been the one to let your best friend know her sweetie hasn't been that faithful. Or maybe you let your crew know you don't think they're making the best decision by sneaking out/shoplifting/playing a prank, etc. Either way, you always have an ear to what's going on and a mouth to express your thoughts. And, as long as your talk is helping (not hurting), what can be the harm?
