Sompsin's "Grey days" is built from short, blunt fragments, almost like a list of things the speaker notices while looking out at a dull day. There are no full sentences and no "I", so the speaker stays hidden, but the feeling comes through the details: a silent, empty atmosphere, wind rushing past, faint whispers, plants with no colour, and clouds hiding the sun.
The poem seems to be about more than weather. Words like "bleak," "cold," "colourless" and "lacking warmth" suggest a mood of loneliness or low spirits, as if the grey outside matches something grey inside. The repeated line "Bleak silence" opens and closes the poem, which makes it feel like a loop with no escape or change. The short lines work the same way, each one flat and heavy, like another dull hour passing. The mood is quiet, chilly and a little hopeless, with the sun only mentioned to show it is blocked.
