Hm, well I don't miss people because of what they brought concretely, but because of the bond I had with them. Yes, also the good times spent together, so maybe that counts as bringing something concrete but idk.
Yeah, I agree it's hard to tell if there's any relation to type here.
I also agree that perceiving functions are less likely to miss things, attachment is more likely related to Fe or Fi. That is, if it's type related at all.
But maybe it's related to rationality? I noticed SEEs for example don't seem to "miss" people, if you no longer interact with them, they kinda "forget" about you, not literally forget, but they just don't seem to attach themselves to people they aeren't interacting with. Your attitude reminds me of that, being their dual maybe you have the same attitude?
I guess it's back to being a J type for me...
