So yeah this is one of those "What should I do?" kind of threads. So a week ago before winter break I ask out this girl I like. And I think she likes me. One day in class I feel someone's foot on mine. I turn to the left and it's her. She smiles at me and I smile back. Also in class she'd jokingly wave at me even though she's right next to me and she laughs at my jokes, even the ones that aren't funny. Also I'd ask help from her with a classwork assignment and she'd help. Then one of my friends would ask her and she'd say no. So like I said earlier, I asked her if we could hang out and maybe watch a movie. She tells me maybe and says she has plans with her family. And I try getting her number but she has limited texting. So I don't know what to do next? Please I need help. How should I follow up?
