It’s definitely up to you to decide how clear and easy Williams’s poems are in general. There’s no doubt that some of his other poetry gets a lot weirder and more experimental. In any case, no matter how strange the poems get, you can usually tell a Williams piece by the way he uses images. Like in this poem, the individual lines are mostly clear and direct. These short lines are meant to create a mental picture immediately. Even if he mixes up the order of the pictures, each one stays in sharp focus. That’s Williams’s style, and you’ll find it all over his poems.
