usually I don't do it in the company of others. Sometimes when I walk down the street and the street is empty I would whisper to myself. But mostly I talk out loud in my apartment, and the walls are not sound proof. So, I guess if my neighbors can hear me, probably they think I'm insane or something. By the way, the scenarios I create aren't imaginary 100%, but rather I imagine how to confront some people based on past experience. So, they are mostly social scenarios.
