How do you manage your system memories?

If any particular headmate fronts at some point, do you treat/feel the memory of that time as theirs, or does the memory belong to the system as a whole. Do you ever feel, "this isn't me, this memory is of another headmate."

We mostly share our memories and we can recall what is experienced by another headmate. Most of our day to day memories are shared and belong to all of us. Though, we firmly know certain memories or events are done by or linked to a certain headmate.
