What is the purpose of couplets in this poem!. Is it to allow a flow of phrasing to better describe the setting!.!.!. or another!?
-Stopping By Woods On A Snowy Evening-
Whose woods these are I think I know!.
His house is in the village though;
He will not see me stopping here
To watch his woods fill up with snow!.
My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year!.
He gives his harness bells a shake
To ask if there is some mistake!.
The only other sound's the sweep
Of easy wind and downy flake!.
The woods are lovely, dark and deep!.
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep
