What I usually see Fi PoLR being is doing their thing(TM) without really thinking how people see you as being in relation to them.
It is like "because my feefees and others have these feefees [or relational needs] therefore the feefees [or relational needs] matches this and in order to contnue with good feefeess there is need for this".
That would be Fi IMO but...
It is like "because just added one to one and got 2 therefore similar stepwise operation is 2+1=3 which is by going back 1+1+1=3 and in general this sort of operation seems to be 1+n". Tat would be Ti IMO.
