Here's a one that you only understood when you were younger; that need to just, not brush your teeth. It's a strange mentality that essentially fosters the angry teenage-rebellion years, but "Go and brush your teeth" is one of the first ground-rules of a daily routine that must be hammered in and and perfected, before you can move on to sending them lawn-wards or trusting them to wash any vehicle without momentarily gaining the power of flight thanks to a pressurised hose. The method of madness many employ to convince their parents a toothbrush has been used is simply to run it under the water instead before placing it back in the holster. However, you must know better. You must ask them to grin like every crazy Pixar-esque animated smile you've ever seen, so you can thoroughly inspect just how much of a porker they're trying to get past you with their lack of any minty-freshness.
