My dad is the best. Every Sunday he comes to visit his gradkids- Seth and Mia. AS he was leaving I noticed something shiny on his slipper. All his straps were screwed in! First thing he said "Its only 1/2" screws." I don't think that you will ever see this in your lifetime. Making the $3 slippah last longer. I gave him some of my slightly used rubber slippers. I figure its better than what he has.
