Here, a speaker describes the moment a friend walks through a door and is introduced to others. The poem is built as a string of questions: did you notice my voice thicken, my eyes soften, my words fill with pride? Each question points to a feeling the speaker couldn't hide. Only at the end do we hear the actual words, simple and short: "That's my friend!"
What the speaker feels is a quiet, overflowing pride in the friendship. The body seems to speak before the sentence does. Voice, eyes and words all change, and the repeated mention of eyes, first softened and then shining with love, suggests how deeply the feeling runs. The poem is also a gentle address to the friend, as if the speaker is saying, "I hope you saw how much you mean to me."
The mood is warm, tender and a little shy. Holding back the plain statement until the final line gives it extra weight, and the exclamation mark lets the joy finally spill out.
