A poem does not always explain itself on the first reading. That is part of its invitation. Start by reading the whole poem without stopping to solve every line. Notice a sound, an image or a feeling that stays with you.
On the second reading, try speaking the words aloud. Listen for repeated sounds and pauses. A line break can make you wait before a word arrives. Ask what that small delay does to the meaning.
Choose one image. What can you see, hear or feel? If the poem describes a road, a river or a closed door, consider both the real object and the ideas it might suggest. Support your interpretation with the words on the page.
You can write a short note beginning with “I notice…” or “I wonder…”. You do not need a perfect answer before you start. A useful reading grows from careful attention, a little curiosity and the willingness to return.
