The second quatrain begins the extended metaphor with the comparison of the anger and the poison tree. Initiating the idea of the narrator cultivating his rage, he waters the budding tree with fear and tears every day and even the night. Still, the enemy does not know of this growing fury. Fear can make a person act out of character and lose his emotional balance. Deceptively, the speaker employs his smiles as though it was the application of the sun to this toxic tree. With charm, he allows no interjection or awareness of his wrath.
