Dad: difficult (I thought burned out ENTP at first but then I remembered he can't stand talking about concepts and he also gets annoyed like the rest when me and my INTP brother are having a conversation, then I thought for a second ISTJ, since he fits the stereotypes, but then there is no way he uses Te and Fi)
Just guesses because I really don't know and my father has passed on. But my guess is dad was ENTJ - all the indicators are there, from his outgoing personality, to his 'bull in the china closet" tenacity, to his poor boy who went to owner of a franchise and an upper middle class life. Mom? I haven't decided yet. She's definitely an "I," definitely "F" but not sure about the other two. I've found the dynamics of my family have changed drastically since the death of my father, and not for the better. While dad encouraged, mentored and rewarded achievement and excellence, without him around to put a stop to it, mom is now enabling a niece of mine who is addicted to drugs, cannot keep the most menial of jobs, and merely visits her own children when she's allowed to. When I try to intervene on mother's behalf (my niece is truly sucking the life out of her), I am "mean." I keep explaining the difference between helping someone become something and helping someone destroy themselves, and finally give up. I am certain my father is rolling in his grave.
