Honestly, the only time having roommates really worked out for me was with an SLI and LSI, but they were childhood friends. I think what made it so great is that we were all pretty independent, but could also be around each other without there being any kind of stupid expectations about anything - except for paying our share of the rent. But we just kind of had fun sometimes and did our own thing the rest of the time. I'd like to say that had nothing to do with Socionics or something, but in retrospect it seems to, compared to living with LSEs and ESEs at other times, which seem to have all these damn expectations about what a roommate is supposed to be...like sharing responsibilities and getting involved in each other lives and shit...

Other introverts are probably your best bet, if they are healthy people.

To be honest though, I'm planning to buy a large cheap plot of land with a long commute for work, since I don't really like being around most people, so maybe I shouldn't be giving my opinion or something, but that has been my truth.

edit: oh and I self-type ILI-Te.
