"Alone" is a pretty smooth go, for the most part—no crazy Shakespearean words, no weird, off-the-wall metaphors. We're also spared any long, convoluted sentences that don't make any sense.
The only real hiccup with "Alone" is the fact that there are, technically speaking, only two sentences, one that goes from lines 1-5, and one that goes from 6-22. Sure, that adds up to one giant sentence, but it's all just a whole lot of "from this and from that" type stuff. You may have to read it more than once, but you shouldn't be too winded by the time you do. Just stick with us and enjoy the stroll.
