You could think of an INFP’s Ne as a loyal servant who walks the perimiter of the grounds carrying a lantern before it and with a guard dog by its side. Maybe the guard dog is Te. The Ne is the face that greets visitors at the door like a butler. Ne checks the gates and doors, and secures the windows. It ensures that its master isn’t disturbed in doing his important work in the study, and it dutifully brings the dominant what it needs whenever called.
Ne the servant sometimes takes his job so seriously that he wanders off the grounds following the tracks of an animal that might be dangerous and picks up scat to bring back to the master, but Ne gets easily distracted and follows another track that crossed the original track. This tracking goes on and on, and the servants backpack gets overloaded with specimens…but miraculously in what seems like aimless wandering it ends up back at its master house. Tired, Ne goes back inside satisfied at having done a good job, gives the specimens to the master and goes to the Ne’s sleeping quarters.
Si is the master’s personal secretary who never leaves the house, and with Ne tired out Si takes over some of the servant’s duties. When someone knocks at the door, Si responds in fear and uncertainty double-bolting the door. Si runs up to tell the master that their is a horrible monster lurking outside, and they try to decide whether to sic the Te dog on the potential intruder. They both cower huddled together in the study frozen in inaction.
Ne wakes up, goes downstairs and answers the door. It turns out it was just a girl scout selling cookies. Ne politely buys some cookies and brings them up to the master’s study with two glasses of milk. The Fi master says he wasn’t afraid and that he was just about to take care of the problem himself.
And here is from a discussion I had with some INFJs:
Fi wants to simply clear a path through the woods, but wants the woods to remain as is. Fi wants the woods b/c the trees enclose the path. Fe sees the woods as material to build a structure w/ in which people can live. Fi wants to build also, but wants it to be unobtrusive. Also, Fi is mostly considering the individual and so it is just making its own way through the brush. Others may follow, but that is secondary. Also, I’d say Fi is making a path into the woods rather than out of the woods. Fe enjoys the woods too, but wants it as a nature preserve that can be used for human needs. Both find value in the woods.
Fe is the missionary that comes to the stone-age tribe of Fis hidden deep w/in the ancient trees. Fe invites Fi out into the open. Fi has never seen the horizon before and runs screaming back into his protective home. The Fi tells this tale of adventure to the excited tribe who listens in awe to his great feats and becomes a hero in the telling. Meanwhile, the Fe is thinking what a strange fellow.
