I live in close proximity to a (very) ISTJ and a (extremely) ENFP. Brothers a year apart.
Just watching them come in the room makes me laugh.
ISTJ: Pick up your socks. You always leave them lying around.
ENFP: Okay... (huge amazed gasp) Look! LOOK! Look at the window!! Whoa... what is this, it's SO pretty! Oh, cool...
ISTJ: It's a luna moth. And it's dying.
ENFP: What? Dying? What do you mean?
ISTJ: Luna moths can't eat. They're born, they mate, they die. This one is dying. Pick up your socks.
ENFP: We can't let it die. Oh, look, K'nex! We can make a K'nex cage for the moth, and I'll feed it sugar water, and... (leaves still talking)
ISTJ: (huffs and picks up socks)
Oh, and ESTJs are lots of fun. Especially when they're married to each other.
(Background: Mary and Ralph are ESTJs in their 50's. Mary wants everyone to eat healthy. Ralph lives on white sugar.)
MARY: Coming to bed, honey?
RALPH: Oh... yeah... I was thinking I could watch Matlock and have a little snack
MARY: Yeah, I know you were going to have a little snack once I went to bed.
RALPH: Yeah.
MARY: Well, you did eat the beets at lunch.
RALPH: The beets were very good.
MARY: Good night.
(Ralph proceeds to go to the kitchen and cut himself a quarter of an angel food cake, put double scoops of ice cream, and smother it with whipping cream. Then he eats it all.)
