A fox saw
the delicious grapes in the vineyard
hung around the fence to eat
between the fence poles
too narrow
A stalwart fox could not enter
to eat the delicious grapes
He decided to fast for a week
and he did
then the fox's body became thin
he easily passed the fence into the vineyard
went in
humming
looking around
watching people sweating from afar
a fox for several days
ate to his heart's content the desirable grapes.
tired of eating grapes
a fox tried to come out
because of his fat
he couldn't get out
then a fox decided to starve again for another week
and he did
a fox
has became thin again,
got out safely
When he got out, a fox sighed
"I was hungry when I went in, but I'm hungry when I leave......."

The fox stayed there for a week
The time when ate the grapes
The fox ate heart's content
He had forgotten it.
