if we meet and I say "hi"
that's a salutation.
if you ask me how I feel
that's a consideration.
if we stop and talk awhile
that's a conversation.
if we understand each other
that's communication.
if we argue, scream, and fight
that's an altercation.
if later we apologize
that's a reconciliation.
if we help each other home
that's cooperation.
and all these actions added up
make civilization.
