As pines are sober
When they stand etched
Against the sky
Hating you shall be a game
Played with cool hands
And slim fingers
Your heart will yearn
For the lonely splendor
Of the pine tree
While rekindled fires
In my eyes
Shall wound you like swift arrows
Memory will lay its hands
Upon your breast
And you will understand
My hatred
It is now clear the fire/arrows the speaker is shooting as a result of her hatred represent memories explaining the history between the speaker and subject. These lines imply that the subject either does not understand the capacity of what he has done to the speaker, or simply does not remember. The personification of memory serves to remind the subject by literally seizing him.
