Going back to my ESTJ step-father and my ESFP brother and I. Neither my step-father nor I understand my brothers need/desire for thrill-seeking and partying into the wee hours of the morning. Neither my brother nor I undersand my step-father and his need/desire to wake up at 5am and work until 9pm, and then get up the next day and do it all over again. And neither my step-father nor my brother understand my need/desire to research things, learn, analyze, and investigate 24/7. We all try to understand each other - we all ask questions, we all make fun of each other - but on some level, we just don't get each other. We understand certain things about each other, but we're always rolling our eyes at each other and the things we do. Am I the only one who has a family like this?
