Our speaker is in the woods, but (gasp) he's trespassing. He first wonders who owns these woods. In the same breath, he tells us that he thinks he does know who owns them. The lucky landowner lives in a house in the village. Phew. So, our speaker won't get into trouble for trespassing, because there's no one to catch him trespassing.
Surprise! Our speaker has a horse (neigh), and this horse is little. Our speaker psycho-analyzes his little horse and supposes that said little horse must think it's pretty strange for them to be stopping in the middle of nowhere, with no one in sight, with not even a farmhouse close by, and absolutely no sign of hay. Newsflash: the speaker and his little horse are chilling (pun intended) between the woods and a frozen lake. Ice skating? Nope. Also, it happens to be the darkest evening of the year.
Little Horse is starting to really lose it. Fortunately, he has some harness bells on his back, and he gives them a little shake in order to get his master's attention. The only other sounds are of a slight wind and of falling snow. Shhhhhh. It's quiet.
Our speaker admits to having a hankering for the dark woods, but he tells us he's got things to do, people to see and places to go. He's got a long way to go before he can rest his head on his little pillow, so he had better get going.
