why do we have "public lives" and "private lives?" is it something about the way society is constructed (normative, so we play by the rules) and/or is there something about the very nature of the human animal to always have some part of itself hidden (to escape control, avoid judgment, or to wield power, etc)? does anyone here live a completely "open" life and has no problem talking about any action? is this a cultural construct? what are is the role of privacy in sociality? also, what are the roles/functions of secrets?
