so there's this boy in the next grade up that I think is reallyy cute, but obviously I only see him in the halls. we have no classes together or the same lunch period because we're in different grades. but anywas, I really want to talk to him, but I don't want him to know I like him. so obviously I can't just walk up to him and be like hey because that's kinda obvious! and he shows signs that he likes me, but I think he is in the same situation here, so I'll just be the first one to make a move but I'm not just gonna go up to him ans strike up a conversation. help?
