I know a guy who is so similar to me that it's spooky. I've met him at a dinner-party twice (mutual friend invited both). His wife is also charming (friendly cute, probably ISFj). Being ENTj, I'm not surprised that my identical is a guy. Even our opinion about the wine was similar and we kept agreeing with each other, despite the gender differences and about 10 years, a job and being married with children. Spooky.
