I agree. I think it's because we process Introverted Intuition ahead of Extraverted Feeling - so sometimes we have to give ourselves rest and psychological space.From experience (I'm an INFJ) we all withdraw, some more than others. It's way to recharge one's batteries so to speak
My interactions with my INTJ friend (who is female and just a friend) seem to be pretty well in synch on it. She's a busy person but seems to have a knack for knowing just how often to check in on me, send me a funny email or leave me be for a while.
This doesn't mean it will work the same for everybody because we are all individuals.
