Watched the movie "London Dreams" recently. The movie adopts a style where one of the characters is also the narrator of the story but, the story he is narrating is just a string of thoughts he underwent during the course of time. It is talking to oneself. Francis Bacon in his essay "Of Friendship" says that we all need friends to talk our hearts out. So that our thoughts are out in the open for dissection and analysis. Self-talk doesn't let you do that fully. It's a way of burrowing aimlessly into a wide open trench.
The other side of the fence isn't so pretty either. The majority of people consider someone talking to them as an opportunity to argue and to prove a point. Conversations should be had for the heck of it. When someone tells you how he or she feels about a particular person, it is not for you to judge their views and tell them what to do. It is more about letting them talk, providing the punctuations in their speech so that they can iron out the wrinkles in their soul.
It actually is easier said than done. It is hard not to advice. It is hard to keep a conversation going without arguments and suggestions. But, it is hard to keep a friendship going with their continual influx.
