So I was at this school dance party, and I was talking to this girl. While talking to her, she said that she is talking to someone so she wouldn't dance with me. I try the best I can do so I can at least dance with her, but it didn't happen. After like 30 minutes of trying she had to go home. She left, but she did tell me I was cute and she enjoys the time I gave her. So what did I do wrong because, in my opinion, I felt like I did everything in my power?
