Question

What are common body languages that show up in teenagers when they are curious about someone in a good way?

Answer 1

Moving closer to the person of interest, making direct eye contact rather than looking away, maintaining a posture of openness rather than protective (like crossing one's arms). It applies to everyone, not just teens.

Answer 2

The best sign is if they smile at you.  If not smiling then check their eyes.  You can tell a lot from someone by how they look at you.  

With the body language as being open, that is another good sign. Plus you can also check the tone of voice.  They will also want to try and spend more time with that person than with anyone else.

Answer 3

Eye contact, Shake their head, ask ?"s back, not much different from adult.
