Introverts are observant by nature. They’re the quiet ones who prefer to sit at the sidelines and observe those around them. And no, they’re not judging people when they do this. This also doesn’t mean that introverts are wallflowers. They can talk your ear off if the topic is something they’re passionate or know a lot about. They simply don’t feel the need nor have the energy to be social butterflies.
As Susan Cain puts it, “We’re not anti-social; we’re just differently social.”
