A Carpenter Without Sandpaper

A carpenter friend of mine is skilled and able. This morning, he was building a new table. He said, “I ran out of sandpaper. I have to get some more. I’m going to take a quick trip to the hardware store.” I said to him, “If it’s time you want to save, it just so happens this morning I forgot to shave. Here, you don’t need sandpaper to begin. If you want to get the surface smooth, just use my chin”.
