Do you.......

I used to. Only some times. Like after reading things or when typing things.

no....

Sometimes, but more often, I think out loud.

I talk to myself all the time, I recently had an arguement with myself (I know, weird, but it's a long story)

Yeah. It helps me think.

I talk out loud when no one's around. I wouldn't call that talking to myself, though, so no.
