Last time I did some exterior home improvements, I had purchased a thirty pound bag of silica sand. Being as indecisive as I am, I found myself lugging the bag of sand around my house, from my back yard to my front yard and then to the back again. This went on for about thirty minutes, or so. Eventually, I came to the conclusion that I would begin my efforts in the front yard, so I reached down for the bag and began to drag it along.
The funny thing was, though, that the thirty pound bag really did not feel like thirty pounds anymore. It was odd, since I was actually getting tired of lugging the thing around it should have felt heavier. Quickly I took a peak down at the bag, on the bottom was a huge tear. I had been salting my lawn with sand all day.
