All items have gravity. That means your pencil pulls on you and you pull on your pencil. Explain why the pencil is not stuck to you.
All items do have gravity, so you and your pencil do pull on each other. The reason your pencil is not stuck to you is b/c we are all on Earth. Earth has the greatest gravity among you, your pencil, and Earth. It has the greatest mass, so it has the greatest gravity. If it has the greatest gravity, then all items are drawn to Earth.
