I just read through this entire thread for the very first time (Thx Sparrow for bringing it back to life)...and I am blown away by how many NFs were 'produced' by xSFJ mothers. My mother is ESFJ. She drives me absolutely insane...but I do love her very much.
My ESFJ mother & INTJ father produced 3 ENFP children in a row & then my youngest sib IxTJ.
I have somehow come to believe that ENFPs were 'produced' by my parents because ENFPs are the only type that could 'survive' the 'craziness' I was raised in. Seriously.
