If men gathered the courage to tell a woman that they like her at first, things would be much easier for men. However, things are not so simple, because they hardly tell us anything.
That's where body language comes into play, and here's what we can read from it:
Dilated pupils
Eye contact is a clear sign that someone likes you, the release of oxytocin deepens eye contact. Oxytocin also causes the pupils to dilate, which is a clear sign of interest. The more dilated the pupils, the more a person likes you.
Accidental touches
People have a need to touch the person they like, that way you know if someone is interested or not. Accidentally touching hands or knees is a signal that the person likes us.
Approaching the person you like with your upper body
People unconsciously gravitate towards people they like and unconsciously move away from those they don't like. For example, if people are sitting next to each other, they will turn their heads towards each other first. Then they will open their shoulders, then their torso, and after that they will lean towards each other, reports Beauty and Health.
