Body language sometimes can tell you a lot about someone's emotions. Also sometimes it's much easier to express your feelings to the people you hold dear. Hugs can be sort of a greeting at times, but when you hold tightly on your arms and don't let go easily, that's something totally different. You can do it in many different ways to express different kinds of emotions. When a guy hugs you with both arms, you can't but feel loved and cherished. You should know how to embrace him affectionately as well.
