Just a few extra moments of thought on this subject from this perspective and it has occurred to my plebian brain that the average person with a likewise plebian brain does not have to ask past this point why a parent would say to another person with beliefs and lack of knowledge of the differences between poo and spit, such as yourself or Linear, RAZD, stay away from my kids!
We plebian but observant and never too cautious parents all learned these essentials in basic training at the swimming pool in infant swim class. Unfortunately many college grads and even California state certified teachers do not know these basic truths yet. they'll figure it out though. Perhaps from migrant workers with dirty hands picking spinach, perhaps from their gay lover with likewise dirty hands that brings them their favorite cup of tea unwittingly laced with ecoli or hepatitus from their own behind.
