Once upon a time...
There was once upon a time a shepherd who had two children, a son and a daughter. When he was on his death-bed he turned to them and said, 'I have nothing to leave you but three sheep and a small house; divide them between you, as you like, but don't quarrel over them whatever you do.'
When the shepherd was dead, the brother asked his sister which she would like best, the sheep or the little house; and when she had chosen the house he said, 'Then I'll take the sheep and go out to seek my fortune in the wide world. I don't see why I shouldn't be as lucky as many another who has set out on the same search, and it wasn't for nothing that I was born on a Sunday.'
And so he started on his travels, driving his three sheep in front of him, and for a long time it seemed as if fortune didn't mean to favour him at all. One day he was sitting disconsolately at a cross road, when a man suddenly appeared before him with three black dogs, each one bigger than the other.
