Ok I’ve been doing this for more than half my life, but whenever I meet someone new I’ll test them in various ways to see their reactions and decide if they’re worth the effort to make them my friend or date them!! for example I’ll asses them by reading their facial expressions, body language, mannerisms, their history of reactions to things, and their personality traits that I can pick up, then I’ll push their buttons, compliment them, and flirt with them, just so I can judge how easily I can manipulate them into doing/ giving me things that I want!
