A friend is someone to cry with during bad times. Everyone knows how great it is to have a friend during your time of need to cry on their shoulder. In reality, people don't like it if you cry on their shoulder for very long. So sign of a real friend is that you can cry on their shoulder until you're done crying. And if you're crying too long, your friend will make you snap out of it. They help you to pull yourself back together rather than just give a superficial "There there dearie" and then going on about their lives. You'll be able to tell real quick who your real friends are during crisis and uglier times of your life. They're only ones still hanging around.

A friend is some to gloat with during good times. We're all raised that it's distasteful to brag and to come across as egotistical. The result is that most of us are afraid to say much of anything positive about ourselves. You're allowed to celebrate a job promotion, a marriage, or birth of a child, but it's supposed to be done with class and style. A real friend is someone that you can call up and spend twenty minutes telling them what an awesome job you just did on a project at work and how you feel so incredibly proud of yourself and they are going to be happy for you. They are not going to chastise you for being arrogant. When you have some serious politics going on at work and you pull of a brilliant career move, your friend is going to cheer with you and laugh along with you as you succeed.

Our bodies send signals of all kinds to those around us, and even to our own soul. Did you know that word psychology is named after Greek word psyche, which is literally study of soul? Who we are cannot be separated from our bodies.
