Why is ENTP and INFJ so compatible?

I ain't asking this in my own community. I need to hear it from your perspective because I don't understand just what it is about us that you like? My INFJ friend told me she likes how extraverted and open I am? The lack of social fear, I guess. Hard to believe anyone would like what others usually consider annoying after a set amount of time 😅

(PS. I know y'all from the ENTP community are mad you can't reply to this. This is an interesting flair)
