(18M) I want to approach this girl that I have never meet before. The only time I could ever ask her out would be a passing period (senior in highschool) she gives me a shy personality based off how she always walks alone with her arms crossed usually looking on the ground. It’s weird because sometimes she will look and me and smile which she does for no one else and then she will just look forward and doesn’t look anywhere else. I want to approach her but don’t know how
