My PDA daughter was eating cheese and crackers on the sofa and dropping crumbs everywhere. I asked her if she could arrange things so that the crumbs dropped onto the plate rather than the floor. This was her solution and I absolutely cannot fault it. 
PDAers can be innovative as problem-solvers and are not afraid to develop unconventional solutions. This is a valuable life skill that I try to encourage; even if the results are often not what I was expecting.
What elegant or surprising solutions have you come across?
