I recently went on a first date with a guy I met online. When I arrived at the meeting point, he was already there, looking at his phone, when he saw me, I saw his eyes look me over really quick (like up and down my whole body,) and then his eyebrows rose and he had a slight surprised expression on his face. He was pleasant enough after that, and the date went very well.
I have no indication yet if he found me attractive (no compliments, no physical advances, nothing.)
So what do you think those first involuntary actions means? Did he find me ugly, or attractive or what?
Looking up and down means he's gauging you as a potential mate. If he did it more than once he was liking what he was seeing. Raised eyebrows mean surprise. He was trying to see "more" of you by widening his eyes. I think all in all he was pleasantly surprised to see you.
