Dear Seddit, I would ask this question somewhere else such as one of the social skills subreddits but I think I'll get a better answer here. Empathy is a vital aspect of everyday life, from friends, to picking up. Because you need to be able to read and understand the people you're interacting with, how they feel, how they're responding to you, etc.

My question is, How do you train yourselves to read people. How can you understand someone when you don't know how they think and process? Basically, how do you empathize with and read people? How do you learn to understand people?

~Sincerely, apathetic symbian
