ESE vs SEI, hmmm. I can't say for sure I know any ESEs closely so it is difficult for me to give an evaluation regarding them. From what I read they seem like a lovable type but I'm skeptical that my dual would be part of the busy busy Ej temperament. Some sources say they can be quite strict about making sure everyone is behaving correctly which is not something I think would go to well with me. I would rather be someone who is relaxed and doesn't take things too seriously. As a side note I noticed I tend to get along the smoothest with Fe creatives. Pretty much all my female friends have been either SEI or IEI. (My males friends are of much more variable types, ranging from mostly LII, ILE, EIE, SLE, LIE, SLI, LSI)
