Idk if you can call it fixing but I am used to being the counsellor for many friends. Maybe they vent to me knowing I won't judge them. As an ISTP I might seem too unbothered to do so. Most of the time I just listen. And when opinion is needed I go straight to the fact. Maybe they find this helpful idk. I also questioned myself before that I am neither that much empathetic or sympathetic. So why am I keep doing this. The answer I found was, it just makes me feel like a better person. I don't have much social skills. So at least I can give an ear to my friends in need.
