"And the fact that you say, that should you practice this 'nasty eastern habbit' of washing your behind after a poop will result with you leaving a trail of dirty water on the floor, leaves me with an awkward image of you either being armless & incapable of positioning yourself properly on a toilet followed with a good wash to rid yourself of "it all"
orrrrrr that your unable to manage basic motor skills to take advantage of free water within the vicinity of where you do 'potty time'"

That tells you how often they practise!!
