Short post, to the point, was just walking down the street on my way to study, when I noticed an attractive girl walking down the other part of the sidewalk. She had headphones in and was walking fast, so I wasn't thinking about approaching her, but she quickly eyes me up and down and then breaks eye contact. I didn't believe it at first, but after the checkout I didn't approach since I would've had to run after her and go ahead of her which isn't my style.

So for the future, what would you do different when faced with a situation like this?
