Riddle. See if You Can Solve It
I can exist in different bodies,
I can tell stories without any help,
I can pop; I can also wander; I can lead some to squander.
I am the same backward & forward when I am only one,
I can tell some what to do, but the funny thing about me is that
I can be useless, too!
What am I?
Good guessing...
