I go to high school, and I like this girl. But when I see her in the hallways, I never know what to do. Do I just say hi everytime, or should I just walk past by and look straight every time, what should I do? I mean I feel kind of rude seeing her then just walk right past by and not saying anything. But then I don't want to talk to her too many times in the hallways and might be annoying. Any advice? Thank you.
