"epiphany" moments about people

Have you guys had "epiphany" moments about people? It can be something super small, like a small action they did, even a sentence, and it completely rewrites what you thought about that person?

I feel like I have this more often than other people, like other people wouldn't take one action and decide a person's character like that, and it often makes me feel like I'm making a big deal out of something.

But I don't just take any action, I take action that reveals most about the person.

I'm not sure if it's because I'm someone who leads by intuition.
