Maybe you’ve seen these words on a poster: “People who think they know everything are very annoying to those of us who do.”
Whether you laughed or rolled your eyes, you’ve no doubt encountered a know it all person at some point.
They make an impression. And that’s usually the goal.
Know it all people crave attention.
Think of someone you know who needs to be regarded as the one who inexplicably knows more than most people about everything.
Shouldn’t be hard to think of at least one.
