I feel as if I don't really know when to talk to a girl. I'm on a college campus so there are tons of girls walking around and I'm not sure if I should approach a girl while she is walking or not. Then I have classes where there are girls to sit next to but it feels like that is way too much time together (the classes are 50 mins usually and there is the time before class so I would spend at least an hour right next to them) Are there specific situations in which I should approach a girl or should I say fuck it and talk to anyone at anytime?
