William Blake's "Thy friendship oft . . ."

Hello,

I would appreciate your personal take on the meaning of the last line of the following poem by William Blake.

Thanks immensely.

Thy friendship oft has made my heart to ache;
do be my enemy for friendship's sake.

It is because the pains of friendship and caring are demanding, and when a friend suffers, those who are his friends suffer as well. He asks, I would think, for him to be an enemy, that way he can be glad to see his misfortune, and not have to feel sad about it.

But more, I think Blake is hinting on that they have had an argument, and their friendship is sour, yet he still has the desire to be friends, yet realizes that is impossible, given what has past between them.

That's my take, anyway. It reminds me of his Poison tree, with the end going

And in the morning glad I see,
My foe outstreach'd beneath a the tree

Dear JBI,

This is very helpful. I am considering using the poem for a chapter opener in a novel. I resonate with your second interpretation, which seem a good fit for my needs.

A heartfelt thanks for your thoughtful reply so late at night.
