I (a man) once met a woman briefly in class at school, and then later that week we hung out for the afternoon. While we werr hanging out I slowly realized that there were actually two completely different people (with vaguely similar appearance and life experience)-- When I struck uo a chat with the second woman and got invited back to her dormitory, I was actually talking to a stranger with a level of confidence I had when talking to actual strangers. If I could somehow replicate this tactic intentionally, I would have been much more successful getting dates at school and in the world. But alas, it was UST beginner's luck (and the charged atmosphere of first week of college, when many people are scrambling to make new friends and romantic partners to replace high school social circle)
