A cautionary tale

It happened one Christmas Eve
As I struggled to fall asleep
I heard a crash from downstairs
So I clambered to my feet

There unconscious on the floor
A man lay dressed in red
I quickly checked his vital signs
To make sure he wasn't dead

Then to my relief he opened his eyes
I offered him a brandy and a mince pie
He thanked me as he stumbled to his feet
As he was lead out the door by the police

So be careful during the festivities
Not everyone is as they seem
And if someone climbs down your chimney
He's there to rob you so call the police
