Ok there must be a lot of *****es at my school because like sometimes when I'm in the hallway during classes when theres not many people in the hallway I see girls sometimes and I don't get eye contact most of the time because a lot of girls are insecure and they just look at like the ground are look away from me. Usually its girls I don't know and I occasionaly say hi. But sometimes they just keep walking on and don't say anything back. What would be a good thing to say to them after that if they don't say hi?
