Brooklynn's poem is about losing a friendship without anyone actually leaving. The speaker looks at someone once close and finds a stranger, so the question "Do I know you?" hovers on their lips, unspoken. The friend, meanwhile, accuses the speaker of forgetting, but the speaker sees it the other way around: the friend is the one who has changed, and not for the better.
The feeling underneath is a mix of sadness, confusion and stubbornness. "Who did this to you?" sounds less like an accusation than a hurt, worried cry. The short, plain lines make the poem feel quiet and tired, as if the speaker has gone over this many times. The line "Change is melancholy" sums up the mood: nobody did anything dramatic, people just drift, and you lose them anyway. The ending is the most human part. When the friend says "Let it go," the speaker answers, "But I can't..." and the trailing dots leave the grief unresolved.
