I can see it when I work. The way I hold things and move my hands is just like Dad, which is not surprising seeing as he taught me.

By the way, those lawnmowers don't work because the rollers in front flatten the grass so that the mower can't get to it. Replace them with a couple of thin wheels and it will work just fine. And to sharpen the buggers you put valve grinding paste on the blades and run them backwards. Just make sure you clean it ALL off afterwards.
