This poem is written by Robert Frost, he was an american poet. His notable work includes A Boy's Will and North of Boston.
The speaker in the poem is traveling at night through the snow and pauses with his horse near the woods by a neighbour's house to watch the snow falling around him. His horse shakes his harness bells, questioning the pause; perhaps this place isn't on their usual route, or he is curious that there doesn't appear to be a farmhouse nearby.
The speaker continues to stand near the woods, attracted by the deep, dark silence of his surroundings. He feels compelled to move further into the snowy woods, but he ultimately decides to continue, concluding with perhaps the most famous lines of the poem: 'But I have promises to keep, and miles to go before I sleep, and miles to go before I sleep.'
