A Poison Tree by William Blake

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 water’d it in fears,
Night & 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 stole,
When the night had veil’d the pole;
In the morning glad I see
My foe outstretched beneath the tree.

The Wicked Hawthorn Tree by William Butler Yeats

O, but I saw a solemn sight;
Said the rambling, shambling traveling-man;
Castle Dargan’s ruin all lit,
Lovely ladies dancing in it.

What though they danced! Those days are gone,
Said the wicked, crooked hawthorn tree;
Lovely lady or gallant man
Are blown cold dust or a bit of bone.

O, what is life but a mouthful of air?
Said the rambling, shambling traveling-man;
Yet all the lovely things that were
Live, for I saw them dancing there.

Nobody knows what may befall
Said the wicked, crooked, hawthorn tree.
I have stood so long by the gap in the wall
Maybe I shall not die at all.
