I have seen ENFJ's cut other's down because of moral principles that themselves do not live up to. For example, calling another woman a slut and then engaging in sexually permiscuous(sp) behavior.
On a smaller scale, my ENFJ cousin does this with the phone & social activities. She will tell me off because I didn't return her call right away, but then won't return my calls for days. She'll also expect that you hang out when she's available to hang out & then make herself completely unavailable for weeks. She'll criticize her friends for going out & getting drunk and then the next night is pounding beers like a pro. It drives me up a wall.
