Isolation can be a pretty lonely affair, but not in "The Lake Isle of Innisfree." The speaker seems to really crave some solitude, and can you blame him? He's sick of the congested city, and the only company he's after is that of the bees, the beans, and the birds. We can relate, right? After all, why do you think people have vacation homes in isolated locations—the beach, the mountains, and, of course, lakes? They want to "get away from it all." Well, so does our speaker, but maybe not just for a week or two, maybe for good.
Why bother going all the way to Innisfree? All this speaker has to do is retreat into his heart's deep core, and he'll be all by his lonesome. Just join a meditation class, dude.
Sure, the speaker wants solitude now, but he will eventually come crawling back to the city in search of a familiar human face. Everyone needs a buddy.
