Well, I mean. Everyone has emotions. The question is what you do with them: how much you acknowledge them, and then how much you factor them into your decisions. Of course, there are side effects to brushing your emotions aside. Unless you empty that garbage pail, it's going to overflow. Here's a bit of a recent conversation with a friend, also INTP:
> I have trouble dealing with situations like that, because I kind of try to be agreeable, but that only works up to a point. And then i suddenly snap. It probably doesn't make sense to the other party. You know, "He seemed okay with what I was doing before!"
* Yeah, I know. The sponge can only soak up so much. There was this moment in high school -- I was in a friend's room, in a kind of bad mood. I was slumped against his bed. Someone sneaked up in the hallway, and shot me in the face with a water pistol. I didn't react. I wiped my face, and kept lying there. He snuck up and did it again. Again I didn't react. He did it a third time, and I flipped out. Before I knew what I was doing, I was up and screaming and raging and kicking things with all my force. I don't know who did it. I guess he said "holy shit" and hid somewhere. But I didn't calm down for like ten minutes.
> What the fuck? Who does that three times? Or even twice?
* That guy.
> Once, i can understand. Yeah, it's retarded, but whatever. But to come BACK and do it AGAIN?
* I don't know.
> That is some fucking pathology right there.
* I know. I guess somewhere in my head, I just excused once. All right, someone's being an idiot. What else is new. Then a second time, fuck, what's wrong with that person? Oh well. But three times, it's like -- what the shit.
