I'm feeling easy like Sunday morning so I'm gonna give a nice meandering answer!

I'm also going to work backwards so hopefully it'll make sense.
Is no person trivial? I don't know but I know I can easily feel righteous indignation over things that have nothing to do with me, with no sense of time or distance to stop the feelings. What I've been noticing with myself especially over the last couple of months is there is usually a need to DO SOMETHING coupled with a strong sense of urgency. You can move people to action when that happens, but it also means some impulsive and not very well thought out reactions that can explode in your face.
I would not generally describe myself as an indifferent or detached person. I am and I present myself as an accessible, tangible person, who has problems and understands people have problems. I like being this way and being this way severely screws with the ability to indifferent. I just don't want to be an indifferent person. Too many people believe "It's not my problem" which is a disgusting attitude to me because eventually it will be your problem. It's not hard to engage me in your problems, although I ultimately decide the level of engagement. Like, I've had a handful of older people ask me to get them something off of a high shelf at the grocery store and next thing I know I have their list in my hands and I'm shopping with them. This guy I was friendly with during a semester class with called me two years later asking for help because he was in jail, about to be deported and needed an immigration lawyer. I was shocked thinking, dude we had one class together is there no one else to help you? I mean I could have "gullible fool" written on my forehead.
So this may be where the indifference comes in. I am starting to prefer the kind of "help" that I give above (fleeting and situational) than the kind that is long and drawn out and will deplete me. Some people have got serious serious issues and I am increasingly not willing to get involved anymore. It's too much for me and the other person's problems take me over and then I've got my own stuff to deal with and I can't do all of it. So when I see something going in that direction and I'm going to get sucked in when I don't want to be I make myself detach. Not that I don't care but I make it out of sight, out of mind. I don't ask the person what's going on anymore or how they're doing or I don't allow them to tell me what's going on by constantly changing the subject or throwing out disinterested body language. Gradually, once I stop getting that stimuli I can begin to disengage with the person. I've done this a few times and I feel a bit guilty but you've got to recognize when you need to cut and run.
I recently experimented with telling a person who was doing this point blankly that I'm not interested anymore. The reaction was interesting, but I guess I'm more interested in my reaction to her reaction than her reaction. It basically came down to am I going to pretend to be interested anymore or am I just going to tell her I'm not. I could keep pretending I am and things would continue as they are and we would be friends in name only. The more pretending I did less I truly cared because I was just going through the motions and my heart really isn't into that.
Dude I'm telling you, leave the FJs alone. Abandon ship.
I've asked people before, how close do you want to be to me? It's like I have to give informed consent, lol. The closer you are the worse it gets. You are my business, your whole existence is my business, there is little sense of when to go away or back off. You're in my little electron cloud. I really don't even know how to advise you how to get this FJ monkey off your back because you'd need an atom smasher or something once you get in that deep. It's the Fe Merge. I think Jung talked about it.
I only do it to my immediate family and two friends and I love these people dearly. I try very hard to keep that in check. It's not necessarily a bad or negative thing although it can become overpowering. When it's good I will tear something down brick by brick with my bare hands if I have to. Things become very clear and I know exactly what I have to do and I'll drive straight down the middle. I'm doing it now with my mother and I've gotten this incredible energy that I have no clue where it has come from. I feel totally engaged, invested, and motivated to make things right. My mother said to me yesterday, when did you get like this? I said I don't know it just happened.
Other positives are you're always in my mind and I'm always on the look out for things for you and thinking of ways to make your existence a more pleasant one. It's very much like that song "I Say a Little Prayer for You."
Bad side is it's very possible for that same intensity to be dedicated to making your existence unpleasant and insufferable.
