Conversation partner

I'm often told that I won't talk about myself.
I'm well aware of it.
I've been since I was a kid.
When I wanted to talk, I missed my chance and finally I had stopped to talk.
As a result, I don't understand what I really want to talk about anymore.

But, recently I've noticed.
Instead of that, I talk to myself a lot.
Sometimes I speak out, sometimes I do in my head.
I guess the best conversation partner for us is ourselves.
