It has a head but it's not a man.
The bigger it is, the less you see it.
It has a mouth but does not speak, it has a bed but does not sleep.
When you say its name, you break it.
It flies without wings and it runs without feet.
I give it to everyone but I keep it.
It doesn't burn inside the fire, it doesn't get wet in the water.
If you feed it it lives, but if you give it water you kill it.
