Do your pupils really dilate when you're attracted to someone?

Question

How do I know if someone pupils dilate or not?

Since it just dilate a little..

Answer 1

Sometimes it happens coz you're the sort to mimic the body language of whoever you're talking to. I sometimes speak with a woman who does that, and I know she is not into me, she's just mimicking me. Not that I'm into her. I'm just mimicking her. :D

Answer 2

Yes, but only a tiny bit so that it doesn't consciously register with the person you're talking to.

Answer 3

Yes, and the other person can sense this on an unconscious level.  Just as you may be reacting to unconscious cues of attraction.

Answer 8
