Dong-sun and chris had a very serious argument during which dong-sun said some very hurtful things to chris. after the argument, he tried to apologize to for what was said during the argument. dong-sun's later behavior best reflects which principle of communication?

It best reflects the principle of "communication is irreversible and unrepeatable".

Communication winds up irreversible in light of the fact that once you said something or do a few gestures you can't take it back. You can be sad the same number of times as you need. Be that as it may, it doesn't imply that what you did or said will be disposed off from the life of the other individual. That is the reason when individuals are angry, they must think many times before saying something they lament after.
