The tree outside my window

The trees like it best
when there's a storm.
The wind gives them the freedom to dance.
The rain gives them the power to sing.
Yet, the human ear simply hears cackles and screams.
Whilst they're having the time of their life,
all we can think is;
are they in pain?
Why do they cry?
Do you think they hurt inside?
Maybe we do this to make our pain more bearable,
because if everything that surrounds us is dead too -
being sad can't all be so bad, can it?
