Knock! knock! knock! at your door, who can it be? not sure,

Unforms worn to show their identity, a disguise this may be.

When they are not whom they appear to be, what might happen is scary,

Do not just open your door, be sure before you become no more.

When there is a knock, a face of a stranger appears on the other side,

A smile of sincerity or perhaps an evil one who preys on the trusting.

When there is a knock, think twice before you gladly open your door,

Friend or foe, it is hard to know anymore as they approach from out there.
