I sing wherever I am, if I feel like singing. So yes, I sometimes sing in the shower. Often I'm just thinking. Sometimes I think things out or ponder deep thoughts, but usually it's just: "first, I wash my face. Scrubscrubscrub. Then my hair, scrubscrubscrub.Then my body, scrubscrubscrub. Mmmm. that smells good. Okay, all done!"
