The one who makes it, sells it. The one who buys it, never uses it. The one that uses it never knows that he’s using it.
Often held but never touched. Always wet but never rusts. Often bits but seldom bit. To use it well you must have wit.
I work when I play and play when I work.
What goes through a door but never goes in. And never comes out?
What can be heard and caught but never seen?
Poor people have it. Rich people need it. If you eat it you die. What is it?
