I met this girl in my class, she is actually in 2 of my classes. We hung out once, for an hour. I socially kinoed her, intentionally touched her face one like a small poke (socially). I really like this girl, but what should I do next? She told me a lot about herself, her school, her parents, brothers, her hobbies. How long do I have to wait before I tell her that I reallly like her? How should I do it? Any ideas?
