Both simile and metaphor are figures of speech used to compare two things. However, there is a difference. The simile is a more direct comparison than the metaphor. It uses words <em>like </em>and <em>as</em>, while the metaphor omits them, stating that something is something else.
As we can see here, in the fifth line, the word <em>like</em><em> </em>is used: .<em>.. or </em><em>like</em><em> a pair of thick socks... </em>This shows us that the poet is using a simile. He compares his poem to a pair of thick socks, suggesting that it can provide warmth and comfort.
