A family of bears had a nice little cottage,

but while it was cooling, they first went to forage
in the woods for some berries and roots.

Returning they found that someone had wandered
right through their house and their porridge was plundered,
‘Who is this visitor,’ the three bears wondered,
‘dozing in our bed in her boots?’

For there she is asleep in the room upstairs,
dreaming of porridge and teddies and bears;
awaking, she sees them, remembers 'here' is 'theirs' –
‘So sorry to be nosey!’
‘Your bed was oh, so cosy’, and away she quickly scoots!

The bears put a sign up, ‘Inside you may not come,
if your knocking brings no answer, and no-one is at home:
this property is private, you are not free to roam,
and we prosecute anyone who loots!’

[IP: take a fairy or folk tale and put it firmly into the 21st century.

I don't expect that this is exactly what was in mind, but the teddies were photographed on my mother-iin-law's bed a few years ago. It has been posted a number of years ago, and was enjoyed, so just tweaked]
