There is not any conversation which could make you to not forsake your interlocutor in virtue of that conversation.
You might keep on talking because of your feelings to that interlocutor or in the name of some rules of politeness, but the elevated subject matters exhaust your power of concentration and the trivial ones cease fast to be taken seriously.
All the words prove to be lifeless or at least to not have that life which can bind two interlocutors.
The humans can be bound together rather through sounds which do not seem to be exclusively human: the moans of sufferance or sexual pleasure keep the humans together for compassion or intercourse.
Since the moans are prolonged imitations of the sounds of respiration and of the beating of the heart, we might say that they attract the men to each other because they reproduce the music of the life itself. Different from the words, those sounds are really close to life.
The communion through moans naturally finishes by itself after a certain time. But the common practice of talking transforms such a natural end into an artificial one, because of the words of compassion or love which interrupt the moans. The communion is broken by them temporarily or for ever. It is often possible to be reversed in cold, conventional words.
We learn such function of the words from our early childhood. We come into the world uttering moans of sufferance for getting mother’s compassion. When we got it and the communion of moans seemed to be continued through moans of love, the moans are suddenly replaced by words. The words come ultimately from the society, not from our mothers and they can be easily interrupted as any other conversation.
Thus, Oedipus’ complex mainly tells about the way we are betrayed by words and secondarily about a refuted sexual relation with one of our parents.
