In [Analysis of Robert Frost’s Snow](https://literariness.org/2021/02/24/analysis-of-robert-frosts-snow/), Nasrullah Mambrol offers insights into a poem that delves into the dynamic of human connections and relationships through dialog:

A narrative in the manner of Frost’s better-known “The Death of the Hired Man,” this poem also presents a couple, Fred and Helen Cole, discussing the plight of a man, Meserve, who at the opening has disrupted their sleep in the middle of the night. Meserve, making his way in a blizzard, has stopped to rest at what appears to be the midpoint of his journey. In the second stanza, he phones his wife to tell her that he will be making his way home from the Coles’ now and to say goodnight before it gets too late. It is clear that his wife is displeased. Only one side of the conversation is recorded, but when Meserve says, “I didn’t / Call you to ask you to invite me home—” it is clear what his wife thinks of his journeying out so late in such dangerous weather. She is silent in response to his tough comment... [--Analysis of Robert Frost’s Snow](https://literariness.org/2021/02/24/analysis-of-robert-frosts-snow/)

What follows are additional observations to complement Mambrol's analysis and highlight Frost's commentary on connected relationships; be they in the 20th or 21th Century.
In contrast to today’s smart phones, where we can control the volume of the incoming ring, Meserve (Me serve?) uses a soft out-going telephone ring:

“I’ll call her softly so that if she’s wise
And gone to sleep, she needn’t wake to answer”.

This is a reference to how little force Meserve intends to use when he cranks the [phone’s magneto](http://oldphoneman.com/FSMagnetos.htm) to create just enough current to quietly ring the bells on his home phone.
The Coles see first hand that it doesn’t take much effort to connect with a neighbor's house.
Meserve’s wife answers the phone, letting us know that she was not “wise” but very worried about her husband. From her point of view, she is probably very thankful for the invention that connects her house with the Coles’ house. The 'soft' connection provides reassurance that her husband is still alive; making all the difference.

Preacher Meserve implies that the Coles’ house is not a ‘home’ because it is “frozen brittle”.
As the poem plays out, we will learn that the telephone is a device that facilitates communication even when nothing is said:

“He lingered for some word she wouldn’t say…”

The telephone is good at communicating what is said and unsaid, but it is only as good as the individuals that participate in the conversation.

Meserve’s house number is maybe “twenty-one?”; just three miles away. Helen Cole is not familiar with the number and doesn’t refer to Meserve’s wife with the neighborly familiarity of her first name.
Frost is a master of what is said…and not said.

Their houses are connected by the phone’s wire, but Frost implies that it is the first time the Coles ever had a conversation with Meserve:

“We’ve found out in one hour more about him
Than we had seeing him pass by in the road A thousand times.”

The town's phone network has at least twenty other houses, but it is not a substitute for the strong connections/relationships of a ‘healthy’ community.

At the end of the poem, Frost again comments on the community’s ‘frail communication lines’:

“Cole had been telephoning in the dark”

"[D]ark" being a metaphor for the weak relationships the poem's readers are privy to.

In contrast to Meserve’s soft touch, Helen Cole (in desperation to NOW make a ‘connection’) apparently cranks the phone so hard she “jars..!” her arm. As if a forceful crank will establish a connection that should have been previously nurtured over the years.
Ultimately, the Coles suffer the plight of the weak ‘connection’ by having to strain for the slightest of sounds to learn the fate of a fellow member of the community.
Alexander Graham Bell’s invention is so good it even transmits near silence as the clock measures time; both present and wasted. Possibly the same deathly silence of the snow that is befalling the community.
“Shouting is no good” at this point. The “Hello”(s) that should have been done through the years may now be too late.
Hopefully, Meserve (and we in our communities) will take up Fred Cole’s invitation to “Drop in and see us when you’re passing.” Perhaps “The thousandth time may prove the charm”.
