How can you tell that someone likes you by their body language?

Answer 1

Read a socialogy book.... ok ok no leg work for you.

1. Eye contact.
Two Flavors:
Over contact: Takes concentration and motivation on the part of the individual usually always due to a reason, ether ego, trying to be big, or love, trying to show they like you
Under contact: Can't keep contact, usually due to being extremely uncomfrontable due to the way the indivdual feels could be a sign they like you could be a sign that they just can't handle social interaction, use your intuition.

2. Body languange
Three Flavors
Body posture, leaning into you, or standing, sitting close, most be motivated by something, at the least be friendly at the most to show you they like you without saying anything.
Feet position, by instinct we have a habit of lining ourselves up with what keeps our attention, look at a person feet while there in a group and see who there really interested in.
Contanct, any contanct by an individual is a sign of some sort of foundness, on the other part if they don't touch you as much but still show foundness, they may just be insecure.

3. Social Behaviors
Two Flavors.
Being overly nice, throwing comments your way, not letting you say bad things about yourself
Being overly unnice, insulting you and throwing bad comments your way, good sign if its constant that they like you and just don't know how to handle it.

Ether way these things are usually picked up instinctaul by use so if your curious at all chances are he does, which is what most people don't seem to realize her, they come on her because there insecurites keep them from doing the only REAL thing to do, WHICH IS ASK HIM!!!!! Don't try and read people in the end no matter what there assumption until you know the whole person....
