So basically, my friend and I went out last night and came back really drunk. Although I was a little bit in my senses, she wasn't at all.. when I was dropping her off to her apartment, and just about to climb the stairs, she pulls me over and starts hugging and kissing me. So I went along with the flow. We had a 3-hour kissing session near the stairs early in the morning. I insisted around 2 hours into the session that we should stop because people were walking past us and I didn't want her reputaion to be tainted, but she wouldn't stop, so I carried on as well... near the end of the session the alcohol had worn off and she asked me how it all started, and then I explained everything to her.. even after that, we carried on kissing for another half an hour or so..
And now the question: how should I initiate a conversation with her the next time we meet or talk on social media? I'm a little skeptical as to how she would respond because she would call me her brother jokingly sometimes.
