I was angry with my friend;
I told my wrath, my wrath did end.
I was angry with my foe:
I told it not, my wrath did grow.
And I waterd it in fears,
Night and morning with my tears:
And I sunned it with smiles,
And with soft deceitful wiles.
William Blake | Songs of Experience: A Poison Tree, 1794 | Metropolitan Museum of Art
