My voice had pretty much changed by the time I was 16. Maybe he goes the Michael Jackson route, and speaks in a whispered falsetto while in character. I went into a Target Store last week and saw Three Bathrooms, Men, Women and Unisex. My guess is the Unisex remains the cleanest and least used room except during extreme shopping times like Discounted Christmas Bargains.
We were camping recently at a state park in PA. There were 3 different rooms in the shower house: Women, Men, and Unisex.
I was tempted to use the Unisex because I also figured that would be the least used and, therefore, the cleanest. But, as a woman, I was not going to put myself in the possible situation of being in there with some strange man.
