Ding-Dong

I was sitting at the computer in the office and Jack was watching a movie when the doorbell rang.

As I got up to walk to the door, Jack yelled, "Hey mom!  Doorbell!  Someones at the door!", as he excitedly came running down the hall.

As I opened the front door I told him, "I know buddy.  Nobody's here.  It's just a package."

I stepped out on the porch to retrieve the box, and came back inside.

Jack looked at the box, looked at me, and said, "But mommy, HOW can a package ring the doorbell"???
