A Poison Tree

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 watered it in fears,Night and morning with my tears;And I sunned it with smiles,And with soft deceitful wiles.

And it grew both day and night,Till it bore an apple bright;And my foe beheld it shine,And he knew that it was mine,

And into my garden stoleWhen the night had veil'd the pole:In the morning glad I seeMy foe outstretch'd beneath the tree.
