I talk to myself while driving a lot. (Um, embarrassing but true admissions.)

I work through problems that way, or larger things going on in my life. (And moving from a 15-20 minute commute to a 5 minute one made that *really* weird. Also, I listen to NPR a lot less now, and I want to fix that one a bit better.)

(I do also sometimes plug my phone in and have there be music that way, but often it's on low and I talk over it.)
