On my way to school.
I love when people stare at me like I'm some kind of freak.
I sing pretty much everywhere. In the shower, the car, while walking random places. I just kind of happens.
i sing in traffic during rush hour, bump up the music, sing along, it passes the time and takes out frustration for the freakin traffic
I do exact same as you! lol Or if I am in my closet (AKA studio)
