I am just an umbrella on a heavy rain.
You may seat at my shadow until the storm is passed,
Or I am passed on the next page,
A page so long that you may need an after, above, before, and under all.

I may be the driver of a very small car.
But I borrow someone's else hands, eyes, heart, and mind to drive it.
I know only the destination, not the way until the next stop.
You may go with me, if you want.
But our car will be crowded as the door is...
