If you spend to much time trying to think about what other people are thinking whether it’s about you or something else it can lead to missed assumptions. When you assume too often without knowing if something is true or not it can often mess up your brain and lead to failure to communicate (miscommunications)! For example if you thought (or assumed) your best friend didn’t want to be your friend anymore you wouldn’t want to talk to her/him: miscommunication. Sorry if I’m wrong
