 small things that can tell you a lot about a person. One, their body language. From posture to facial expressions to hand gestures, researchers believe that our body language and nonverbal cues make up to over 65% of all communication. Two, their social media accounts. Their social media presence shows how connected they want to be, while their privacy setting shows how much they're comfortable sharing with people. The pictures they post or share tell you a lot about what they like, whether it's going out with friends, eating good food or watching movies. And the things they tweet about can give you a lot of insight into their likes, dislikes and opinions as well. Three, the way they dress. Those who dress casually are often laid back and easygoing people who value comfort over style and don't care much for impressing others.
