The Ambush

Thunder doesn't lead to rain
In every single case.
At times, it just announces
A disturbance taking place.

I guess it's like the way a growl
Implies a close attack.
It might be just a warning
With the consequence held back.

The same applies to life, for we
Might heed a false alarm
And then discover what we feared
Caused not one drop of harm.

The ambush or the sneak attack,
Without its warning boast,
Is what we never do expect
And what should scare us most.
