"People flicker round me"
The narrator of this poem is thinking about the so-called "flames of life", and makes frequent references to flames because of this. This reference is one of those included, as the people flickering distract her from the real fire of her own life. This line from the poem may not dramatically develop it, but it certainly gives a sense of Lawrence's writing style.
"It ought to be lovely to be old
to be full of the peace that comes of experience
and wrinkled ripe fulfilment."
A beautiful developing opening line on Lawrence's part, the reader immediately gets a sense of what the poem is about. The last line of this stanza refers to "wrinkled ripe fulfillment". Using contradiction, since fruit is either wrinkled or ripe, not both, we get a sense that, in the human world old age has the qualities of something as insignificant as a fruit, but the execution of those qualities is much broader and more significant.
"Softly drank through his straight gums, into his slack long body,
Silently."
These two lines from the poem "Snake" emphasize the silent beauty that the narrator finds in snakes, as the words "softly" and "silently" are used here and frequently in other places in the poem. Most of the poem is describing all of the simple things that a snake does, and how it is done so brilliantly; this is just one impactful example of the majestic writing of D.H. Lawrence.
