Hammering a nail isn't exactly the most difficult home upkeep task, and I'm sure you can do so in your sleep. But can you hammer neatly? If you adhere a couple of pieces of tape to your wall, before you begin banging away, you will prevent any marks or cracks in the drywall or paint when you're hammering. Once the nail is set in place, you can just peel the adhesive, and it will tear off around the nail, leaving your wall as clean as whistle. How about that for home schooling?
