When considering two part f devices in this poem, this would then be the following:
How much this person would appreciate thee.
And why she would appreciate thee.
I wanted to discuss the first one.
"How much this person would appreciate thee.".
She would appreciate this thee very much as when see said in the poem,
"I love thee with a love I seemed to lose
With my lost saints. I love thee with the breath,
Smiles, tears, of all my life; and, if God choose,
I shall but love thee better after death."
This would show and support to why she would have respect and appreciation for thee.
Now when considering the second device, we can see why she would love this thee.
We can see based on the following:
"How do I love thee? Let me count the ways.
I love thee to the depth and breadth and height
My soul can reach, when feeling out of sight
For the ends of being and ideal grace.
I love thee to the level of every day's 5".
This would then show why she would love the thee.
And based on all of this, the relation to this would be the fact that this person would love thee, and why she would, and how she would love it until the day of her/his death.
