Body language may provide clues as to the attitude or state of mind of a person. People who show their body language to you can reveal their feelings. The technique of "reading" body language to know if someone loves me or loves me not the position of the feet is used frequently.
Loves me or Loves me not can be indicated through the position of the person's feet. If the toes are pointed directly toward you that person is planted in your life. If one foot is positioned to the left or right, that person wants to leave your personal space.
