The child

Leaning against a huge wall
A child was playing with sand,
Built a castle
But was constantly
Building and breaking
The borders that surrounded it.
The child then looked at the wall,
Gave it a punch,
Ouch! It hurt.

Meanwhile the waves came,
Took the castle away;
The child didn't cry
Waited for the sands to dry,
The hands did pain
But the child started
The work again
With the thought,
Maybe true or false
There must be a palace
A golden garden
Beyond those weirdest walls.
