I row quickly with four oars but never comes out from under my own roof.
Though desert men once called me God today men call me mad. For I wag my tail when I am angry. And growl when I am glad.
In my life I must bare, my bloodline I must share. What am I?
When I am caught I am thrown away. When I escape you itch all day.
What is always coming but never arrives?
