Have you ever experienced this "piecemealing" of targets as simple physical interference. For example at a wedding or other gathering, where various targets might actually share the fragments of their interactions and thereby produce a profile, the S keeps up a running interference. They slice up the party by cutting pathways through the clusterings. This is done by simply marching past on "official duties" but close enough to impose the presence. It appears as polite interjections, superficial enough not to be obnoxious but demanding enough that it interrupts the dynamic of the conversation. Or it can be a form of intimidation. I often like to sit by myself as I practice keeping myself to myself. S's hate that because it is a overt demonstration of independence. I often tag a S as the one who cannot bear to see me enjoying my own space and they can be seen "buzzing" me. This form of harassment can be quite subtle even as sublte as just leaning in to listen in to your conversation with another such that you become aware of the boundary violation on the periphery. There is nothing you can do about it. No one else notices but it changes the communication you have had with the other target and it subtly says "No one communicates here without my permission."
