I'm pretty sure that INFJ's and ENFP's are supposed to be the ideal types for each other. That's what I hear a lot. It seems like ENFP's (along with other INFJ's like me) just sort of gravitate towards me. A lot of ENFP's I see seem to love INFJ's, and vice versa. There just seems to be something special between these two types, and I hear a lot of good stories about the two being together. Whenever I see an ENFP, something... goes off in my head.
