Of course there is matter for remark in poems. Nobody denies that. But it must be solemnly laid on everybody in this world to make his own observations and remarks. That's what we mean by thinking, and that's about all we mean. A teacher says to a pupil "Watch me notice a few things in the next few months: let's see you notice a few things too."
You've often heard me say - perhaps too often - that poetry is what is lost in translation. It is also what is lost in interpretation. That little poem means just what it says and it says what it means, nothing less but nothing more.
