Why did she keep smiling at me ?

A girl I never seen before in the gym kept smiling at me. I got my weights and sat down and saw her and she kept smiling. I look away and back again she just kept looking at me smiling over and over again.

Maybe you had something on your face, or you reminded her of something funny? She could like you or find you hot and that may be her way of showing it but I think it's a little strange..

Why didn't you ask her?
