My mom's an ESFJ as well... I know a couple of other ESFJs and you're right, though I would never have put it that way before, that FE vs. FE smackdown can get ugly! LOL!
ESFJs: Definitely not ones for the abstract at all, and a little too "what's in it for me" for my taste sometimes. And personally, I really can't take that much socializing. It's absolutely n o n -s t o p. They drag you along to parties and then LEAVE you in a crowd. Of strangers. Ugh.
But on the plus side, the ESFJs I've known have also been very warm, very friendly, hardworking and ambitious, which are all very nice qualities, I think.
P.S. In case I didn't make it perfectly clear, I do think ENFJs are wonderful people, and I love my own ESFJ mother a lot, and if you love an ESFJ, go for it! Just watch out for the party thing, and get used to having a lot of people around.
