Before his death in 1990,Dahl confided to friend Brough girling about the meeting between himself and Ms potter
Speaking to wales online ,mr girling said Dahl told him that when he was a boy he persuaded his mother sofie to travel to potter's home in north England .
He told me he want with his mum when he was six .he asked if he could go and see where she lived .
So they went up to the lake district .he come to the farmyard and recognised it ,which made him very nervous .in jemima puddle -Duck the farmyard was actually Beatirx Potter's farmyard and he recognised that.
"He said it was like stepping into a page of one of his favorite books.
"Than he saw Beatirx potter's ,this old woman in her grande. and she said to him 'what do you want ?'
"He said' I've come to meet Beatirx potter's ',and she said ,'well, you've seen her .Now buzz off!'
"His wife said it's actually true .Roald had told her .and it's true Beatirx potter's was quite grumpy and not fond of children .he would have been six and she would have been about 80."
