Interpreting other peoples personality types

I love this game. I always leave meeting new people thinking "I wonder what they they are... I MUST FIND OUT!" I usually start E/I and then go T/F, but if I sense a connection, I gladly skip all of that and focus on N/S. I think I do this because I assume most of the people I meet are likely going to be S since that is how it has been in my experience of life. All S unless proven otherwise.
