My seasons.

When the seasons change,
Who forewarns the trees?
Who makes their branches sturdy,
Who prepares them for the breeze?

When the snow is scheduled to come,
Who tells the birds to stock up?
Are they told to layer their nest,
Or is their survival simply luck?

When the sun begins to scorch,
Is there a call to alert the slugs?
Does somebody order their movement;
How come we dont lose the bugs?

My point is that seasons change,
But nature always seems to be ready;
So when it comes to my seasons,
Will my balance also be held steady?
