The Internal Conversation

There's a non-stop conversation with myself taking place in my head. Sometimes I move my lips, and when I think I'm alone I'll often catch audible whispers. The most inconvenient is when I walk into the restroom and work having a conversation with myself at audible levels and then I discover someone else is already in the restroom. The best exit I've found is to begin humming as if I was singing a song to myself instead of just chatting away. And when someone's locked in the stall and they've overheard me, then it's like a race to use the restroom, wash my hands, and leave before the person comes out and sees me. In those cases I'll also wrap up my internal conversation as quickly as possible without being rude.
