Another thought occurred to me. Ladies, do you "hover" over a toilet in the ladies' room that has (theoretically) never been sioled by a male? And if so, why?
In my many years of experience working in a laboratory that requests urine samples from males and females, I can unequivocally state that females are just as prone to leave a mess or sprinkle the seat. Furthermore, I have also found that some females have no intention of cleaning up after themselves, just as with males. There is virtually no difference in the sexes when it comes to bathroom ettiquette.
