You have me today,
Tomorrow you'll have more.
As your time passes,
I'm not easy to store.
I don't take up space,
But I'm only in one place.
I am what you saw,
But not what you see.
What am I?
I run over fields and woods all day. Under the bed at night I sit, never alone. My tongue hangs out, up and to the rear, waiting to be filled in the morning. What am I?
I dig out tiny caves, and store gold and silver in them.
I also build bridges of silver and make crowns of gold.
They are the smallest you could imagine.
Sooner or later everybody needs my help,
yet many people are afraid to let me help them.
What am I?
