Outwitting faeries...

There lived at Rothley in Northumberland a very clever little boy that 

once outwitted a faerie girl. 

One night despite his mothers warning that the faeries would get him

 if he didn't go to bed, he stayed up alone playing in front of the fire. 

Down the chimney flew a beautiful little faerie girl and joined 

in the boy's game.

'Ainsel' was her name she informed the boy and he, being rather quick 

and cheeky, said he was called 'My Ainsel.

They stayed playing together until the fire began to die down, the little boy 

stretched and rose to stir the fire with a poker. One of the embers fell on 

the faerie's foot and as she screeched out that she was burnt, a voice echoed

 down the chimney asking who had burnt her daughter's foot. 

With a cloud of soot the faerie's mother stood before the little boy asking 

again who had burnt her foot.

'My Ainsel, My Ainsel!' she crowed, delighted that she would get the 

little boy into trouble.

'Then in that case,' said the mother. 'What's all the fuss about?'

And with that she shooed  her protesting daughter back up the chimney.
