Can’t hold eye contact. Oh boy. If you’re one of those guys who can’t stand to look into another person’s eyes when you speak, get over it quick. When you can’t lock your gaze on someone, you look deceitful. You look like someone who shouldn’t be trusted. Even if you’re lying through your teeth, if you look someone in the eyes when you do it, you have a better chance of them believing you.
Body turned away. You guys should recognize this one. Women do it when they’re just not interested in you. Well, when you do it, it conveys the same message. If you’re talking to someone, it’s important to face them squarely. It’ll make them think you take them more seriously. It’s sort of a sign of respect. You may hate their guts, but at least you won’t appear to.
