William Blake: 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 sunnèd 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 stole

When the night had veiled the pole;

In the morning, glad, I see

My foe outstretched beneath the tree.
