The power of a pencil is what you do with it; like erasing mistakes you accidentally write with the pencil.  Another feature of a pencil is drawing. You can draw anything your mind desires like a taco cat or a pizza dog. You can also write anything with a pencil, like the Declaration of Independence or a cool novel. There are different types of pencils like mechanical ones, wooden ones, or ones you draw with on a tablet. What you do with the power of a pencil is your choice. Use it wisely.
