Sorry Freddie, but I just can't stand that. I will not use a locker room that permits young children of the opposite sex in them and I will complain to the management if I see it happen.

I'm not your sex-ed class and I resent being made to be so by proxy.
It's not my job to show your daughter what a naked adult male looks like so don't make it my job. It makes me extremely uncomfortable because one wrong look, one innocent movement, could make it look like I or anyone else in there, is acting inappropriately. That's not a fair position to put anyone in.
