Today marks 4 years since this experience happened. When I was in college, a friend of mine invited me to a pub to celebrate her birthday with other friends. Hours later most of us were pretty drunk, and then my friend started to flirting with me. She touched my leg and asked me “where’s my birthday present?”. She wasn’t attractive to me at all, and I wasn’t sure if I was attractive to her until that moment. At first, I didn’t know what to do, so I just ignored her for a while. After midnight, everyone was leaving and only a few of us remained in the pub. My friend realized that she didn’t have her apartment door keys and her roommate already left the pub and didn’t answer her phone. So the last few of us took her to her apartment but we noticed that her roommate wasn’t there, we assumed she went to her boyfriend’s house. Since I lived a few blocks down the street, I offered my friend to stay in my apartment for the night, she accepted. So the other guys left and we walked to my apartment. But still I wasn’t sure what to do if she started to flirt again with me.
