My ex neighbor is an ENTP, one day after a stressful day at work he recounted a story that involved his now deceased mother. He broke down in tears at one point, I felt very awkward. He was often emo, ok daily, usually work related ¨oh woe is me, my life sucks¨ while never taking solid steps to improve his lot. Reminisced a lot about his younger days when he had $$$. Definately working on his Si imo. He was older, late 40s.
When not doing his math tutoring online or posting math help on some website he was a fun guy to talk to. We could take any subject and run around in circles for hours without really deciding or concluding anything. Fun. He laughed a lot when we´d have those sorts of discussions.
