Hello. Unfortunately you did not enter the poem your question refers to. This makes it impossible for your question to be answered. However, I will try to help you by showing you how to make the poem summary.
First you will need to read the entire poem and understand the main message it conveys. Some poems are difficult to understand, especially when they have a very subjunctive language. In this case, to help your understanding of the poem, you can search for blogs or articles that present an analysis of the poem, where you will be able to read an interpretation of the poem and understand the subject and message it presents to the reader.
When you understand the subject and message, you will be able to write a sentence about each of them, which will be your summary of the poem.
The subject of the poem refers to what the main element that the author is working within the poem and the message, refers to the lesson that this subject can convey to the reader.
