Warnings

Mosquitoes buzz to let you know
That they're about to sting
And snakes with rattles shake them
So you know the pain they'll bring.

Skunks release their special scent 
To warn you, "Stay away!"
And bears stand up and growl to keep
Their predators at bay.

There are certain creatures, though,
Who silently attack,
The way that certain humans do
Who stab you in the back.
