A human life

 A human life is like a tree

it grows, it withers, and it dies.

As the human grows they can be the shade for their future family,

or they could be the reason why the family is miserable.

Like a tree a human can be sturdy and strong or they can be weak and fragile,

It just depends on how these humans want to live.

So be like a tree and grow strong and study so you can provide shade

To protect what you hold dear.
