Explainnation of second and third stanga
Of I am the tree by deneus British
Answers
All of this action is taking place at night - the change is profound, of roots and all, the whole tree - note the imagery and sense of physical movement in the second stanza :
work/disengage/strain/stiff/shuffling/moving
and the extra clue in line 14 gives the reader more clarity, that simile like newly discharged patients surely suggesting that the trees were sick or unhappy, in need of medical help and healing, but now they're healed and free to go and live their lives.
The third stanza introduces the speaker for real, in first person. Here is a woman, the reader must presume, writing long letters (to whom?) and remaining aloof from all this tree action. She doesn't bother to mention the quiet revolution, or rather, she scarcely mentions it - which means she does acknowledge it but isn't that surprised by it?
hope it works
She has seen it coming perhaps, she has known for quite some time that the trees would one day break out. As this exodus takes place she can still smell the remains of the trees - like a voice - that turns into whispers in her own head? The whispers are the last messages of her old life, soon to be renewed.
