...or, you know, the older folks too. If you still do it.
The thought came to me just this morning. In relationships (platonic or romantic) looking back I find that when I have felt wronged or attacked by the other person, I instinctively withdraw into myself and cut all means of contact with them during this time. In some ways I feel that in doing so, I'm "hurting" them so that they feel as dismayed as they have made me. But mostly it's to retreat and have the time and space to ruminate.
Example: If I've had a heated argument with my mother, out of spite I'll ignore her phone calls, or quickly hang up. This will ensue for about a day (or shorter, depending on how I feel).
Another example: When I was PMSing, there as one evening where my partner didn't have the means to contact me (I won't bore you with the details). I came to the irrational assumption that their actions were deliberate, and that they could contact me but didn't want to. After a while of dwelling on this, I remembered days when they couldn't talk to me for long, and I justified that as finding me dull and leaving early, rather than the reasons they gave. So, rather than reply to their apologetic email, I ignored it and refused to contact them for a number of days.
I can't remember any other poignant examples, but when I'm offended my natural response is to sulk. Are younger INTPs prone to this? If you're an older INTP, have you had a number of sulky episodes?
