Actually, even intimate conversations involve scores of beingnesses which each of the individuals in the conversation have crafted to inform them of viewpoints in the universe. Usually these are viewpoints one does not care to own properly.
But even from the view that all that is contained within the individual, and all part of a "someone" there is still an interesting cross-management of communications going on. This is especially true of close or important connections (e.g. with lovers, children or those armed with lethal weapons who seem likely to use them on you).
This cross-management consists of the creation of costume of "Him/Her" by "Me", and his/her monitoring of that costume; and his her including that monitoring in his/her creation of the Costume of Me and my monitoring of his/her costume of Me and including those considerations in my creation of a costume of him or her.
This interchange is what the focus of attention is mainly on in a conversation that involves two people in close exchange. In more socially deceptive conversations where you can't tell if what you're saying means anything to someone or not, the number of identities talking back and forth can be countless, as the genuine communication is occurring in the ranks of Universe as created by two beings neither of whom are really paying much attention to what their bodies are doing at the moment.
To communicate wholly with another, free of costumes and as All-from-here speaking to All-from-there is an enlightening and sadly rare event. It requires an honest and integrated awareness completely free of the gamey conditions which make up the kafuffle of ordinary talk. Here you will find Nemaste, the salute between spirits and the communion of infinities in discourse.
