"- I am all alone, and I have no home.
The fox cub has an earth, the turtledove has a cosy
nest; the little harvest mouse
has an hiding place in wheats, the mole
has tunnels and the cat has a cushion!
But I, I have nothing...
- Don't cry, little turtle! Raoul says.
Look at me: a shell and sky for roof!
Like me, you can walk around the world,
sleep under the stars, you are always at home:
you have your house on your back! Above all, don't be
unhappy: life is sweet
to travellers!"
