So last night I was at a club meeting for school, and afterwards we had a pizza party and I met this one girl who is a friend of a good friend of mine. Afterwards there was a school event that night that a lot of people were going to but we had like a half an hour to kill. Long story short my friend who introduced me had to go take care of something for that event, and I started talking to her. Oddly she had a roll of toilet paper in her backpack because she brought it to blow her nose during the night but didn't use it that much it so jokingly said oh I think that would look good on someone's house that I know of (my ex lol). She then proceeded to ask me who and then insisted that we go do it together. Keep in mind I just met her. She drove me there and we both tp'd the house and on the way back and forth we had great conversations about life, school, and a lot more. I didn't have to try to keep the conversation going, it just flowed really well. I was able to be myself and I felt like we had good chemistry (both chill, agree on almost everything, etc). Once we got back to the school for the event I sat with her during it and afterwards got her number. I texted her today but she has not responded yet. Please let me know a good plan of action to give me the best shot at landing her. My problem in the past is that I've waited too long and haven't been decisive enough so I don't want to succumb to that. She told me she has sort of a "1/2 Bae" right now but isn't dating anyone. Thanks in advance for the help!
