How to tell if someone likes you by monitoring their body responses:
Looks for mirrors; if he/she begins to mimic your movements during conversation, he/she likes you. This doesn’t tell you to what extent, but at least you know he/she doesn’t hate you. If his/her feet point toward you when his/her attention is elsewhere, he/she likes you.
Read the palms; face-up palms means the person is subconsciously telling you that he/she is open to a relationship.
Scan the eyes; when people are physically attracted to someone, their pupils dilate (become bigger).
Look for the Shy Di smile; this was Princess Diana’s trademark smile, characterized by the eyes peeking up as the forehead is bowed. This smile is an unconscious gesture of flirting. ALSO: Check the corners of the eyes when the person smiles at you; a genuine smile will cause crinkling, while a polite smile won’t.
Watch the shoulders; lifting both shoulders up is an automatic muscular reaction when a person meets someone he/she finds to be attractive.
