I noticed this old man having conversion with himself.
I am not sure if talking out loud to yourself is some kind of disorders like schizophrenia but this probably has something to do with loneliness or neglect in the later part of life when you need care and someone to talk to and share your feelings.
There is another side to this. Geniuses like Albert Einstein talked to himself. May be this helped him in clearing his thought process.
Have you noticed anyone in your daily life-like this and what are your views on this?
Third eye view 
I talk, or mumble, to myself sometimes. Can’t say I answer though 😉 I used to think it odd but that impression has faded. I also talk to my dog, cat and horse.
I thinks most of people think aloud sometimes and is normal
My view or perception doesn’t matter. What I think doesn’t decide for another their own status mentally.
I talk to myself often. When I was sitting in a Dr’s waiting room today, I yelled out “oh no” when I accidentally deleted something from my phone. I looked up to see everyone in the waiting room was looking at me. Some people gave a little chuckle, others just stared.
We all have such moments sometimes as a spontaneous reaction
I think that most of us feel it would seem a bit odd to be seen talking to oneself; therefore, we do it in private. People outside of the social norm don’t care about that any more.
True. Everyone feel odd talking aloud oneself in public. As long as it is done in private it is fine.
I talk to myself a lot, I tell myself story to help me go to sleep or to stop me from being lonely. My mum says that imagination is a very important skill.
I don’t think talking to oneself is a sign of a mental illness.
Thank you for sharing this Shailendra.

Thanks Kailani for sharing your views. I also do not think that talking to oneslf is a sign of mental illness and if one does not have a friend to share thoughts, one can talk to himself in private which can help in clearing the thoughts and also as you rightly said can improves imagination.
Lots of people talk to themselves. People involved in public speaking, helps them to remember what they want to say. These days most are actually on their mobile phones so not always a sign of mental illness !
Everyone talks to themselves. It’s just a question of whether or not you do it in a way that other people can notice. I talk out loud to myself sometimes because it helps me think. I just usually do it in my room or alone somewhere. I’d say it would just be when/ how you talk to yourself and what you talk about that makes the difference between crazy and normal.
True. I appreciate your sharing thoughts so candidly!
