There's a girl I met at a party since she was visiting the city with her friend who was my classmate, and there's this girl who was hitting on her and eventually kissed her when I was walking them out. We had talked throughout the night and stuff and I was hitting on her too and when I had walked them out, I didn't know she had kissed the other girl, so when I had said my goodbyes, my best friend rushes out of the door and tells me "that other girl kissed her, you have to go and make your move". I hadn't intended on making a move at all other than texting her the next day, but something took over me and I ran down 7 stories of stairs just to catch her outside the building lobby and stumble over my words with something like "hey uhm I know that she kissed you and I uhm.." and I walked up to her and kissed her right then and there.
