Anger is a virus
That needs not even air
To propagate contagion
Whenever it is shared.

Anger can't be placed in quarantine
To contain its vicious spread
For anger feeds upon itself
And burns a flaming red.

Anger is all consuming
Anger does not desist
From destroying sensibilites
In that haze of its red mist.

David Keig
