How exactly can you stop being so nervous around girls and actually look them in the eye when passing by and in general stop being nervous around girl or in a line and not look away? Because i had a incident when i was looking at a girl and she smiled at me and i just gave her a blank face because i was nervous and didn't know what to do and the second time i looked away. If i was looking at a girl and she catches me what should i do and how do i stop being so nervous? Should i smile? I heard smiling is a unattractive trait for men.
