I think it is probably more like she shares her brain with you @Questingpoet no?
if INTJs were a food they would be a chocolate cake with chocolate icing filled with chocolate bits.

I know a whole boat-load of INFJ's and I pretty much like them all. I mean there are certain qualities about INFJ's that I can never really understand and undoubtedly the feeling is mutual. But in general INFJ's sort of understand me and I understand them. Personally, I find that there are a lot of shared interests between myself and the INFJ's that I know at least. So I would say friend. Besides, I think all INTJ's secretly want to be an INFJ. But they will never admit to it.
I think we wouldn't mind being either INFJ or ENTJ. The F so we actually understand people, or the E so we don't over-analyse and just do things. We couldn't be an S or P; that's just too flakey for us.
