There's no half-singing in the shower, your either a rock star or an opera diva. -- Josh Groban.
I don't know. I think I might be a Rock Diva. [Or an English teacher. "your"?! How about "you're"?!! As in a contraction of 'you' and 'are"?! Sheesh.] I will say that occasionally I hit a note that reverberates off the tile...and I just want to sing it over and over again, composing my own melody to highlight it.
