Do you talk to yourself when you're alone?

I really don't know if this is a thing. I'm always hearing people describing that they marriage things and speak out loud when they're alone.

I do not. I have a half dozen voices in my head rapidly monologuing or critiquing or waxing nostalgic, all competing for volume, and unless I'm speaking directly to another person, I tend not to be vocal when it's just me and my phone secretly recording everything it hears to give me more enticing advertisements.

Generally, the only thing I verbalize when I'm alone is "Fuck off!" when my brain's constant stream of running highlights of my life's most shameful moments finally hits a nerve that causes that reflex reaction.

Kinda curious if this is a common experience or not
