This embrace is popular among couples, family members, and close friends. It also offers protection for couples, especially when a guy does it to his lady. The back is a sensitive area of the body, and the sensation of it being caressed is quite attractive. This embrace is most effective at times of despair or stress. When one person is more eager than the other, this embrace occurs. It signifies that one person is making an effort to hug someone who does not want to be touched. They don't even raise their arms to return the hug. This is an indication of a one-sided relationship. This is also true of friendship.
