It would be a true tragedy if your daughter would subjected to excrement that came from the bowels of someone different than yourself and deposited into a toilet that resided in the same facility that she went to!  No one should ever be subjected to such horrors.  

And we can all tell how cereal you are too - people that talk as tough as you on the internet are all way cereal.  Perhaps a third bathroom choice could be in order for someone like yourself....the 'super-duper tough manly man bathroom'.  I'm a man myself...but clearly I'm not as tough as you - so excrement that comes from my bowels should not be in toilets in the same facilities that you may visit.
