What regret does Robert Frost voice in the poem “Stopping by Woods in a Snowy Evening”?

The speaker in Robert Frost’s poem “Stopping by Woods on a Snowy Evening” voices his regret that he won’t be able to wait there in the woods for long. He would love to see and enjoy the beauty of the snow-covered woods for some more time, but unfortunately, he has a long way to go before he sleeps.
