You don’t need to be a psychic in order to read people’s minds. Those around you constantly give away their thoughts, feelings, and intentions without even realizing it. You just need to be really attentive to see right through them. Obviously, everybody’s different, each with their own mannerisms and peculiarities. That's why it's so important to understand what behavior is normal for a particular individual. Slight changes in their behavior or body language can speak volumes and allow you to read them like an open book. Analyzing all the information you have, you'll be able to understand someone’s personality a lot better without even spending that much time with them. In different cultures, there can be different rules. For example, in some countries, people look away to show their respect, not because they’re hiding something or feeling uncomfortable. They say you should never judge a book by its cover. That’s good advice and all, but a person’s appearance really can tell a lot about them. We like to spend more time with people who share our interests and personality traits. Watch who someone spends most their time with and how they treat other people. See if this person tries to make others comfortable or rudely annoys people without even noticing it.
