I am sensitive to peoples "energies" per se. Given that you're more extroverted, you will be more inclined to be social. You'll go with the eb and flow of social situations, and I'm sure you manage that well. I had to work a little harder to try and understand emotions, facial expressions, attitudes and tone of voice, behaviors and mannerisms. I find these to be very helpful in gauging other people. Maybe I am over analyzing, but I really just sit back and observe. Some people I'll approach, others probably not, but that depends on the situation.
And thank you! I find Hubski to be much more refreshing and substantive than Reddit. Although the subreddits are what make reddit, it seems that those, too, are filled with nonsense.
