A Guided Tour Around The Swings

You come into the playground,
And want me to explain how things work?
No problem!

You see that sandbox over there.
Cover your head entirely with the sand.
Go ahead...
Do that and then raise your arm,
Until I come over...
To dig you out and pull you through.

And then I will take you on a guided tour,
Around the swings!
How's that?
