There are also some forms of body language that can be universally read with the meaning, I am interested in you or I like you. Sometimes this kind of body language is used unconciously between two people. These signs of interest include standing or sitting with both feet flat on the ground, mirroring or using the same gestures as the other person, and turning one's body to fullyface the other person. In addition, a person's pupils will automatically become wider when they are interested in another person.
