This is a single line, and its power comes from how little it says. The speaker tells us that the day they met someone no longer means anything to them. Nothing else is explained. We don't know who the other person is, whether it was a lover, a friend, or someone else, or why the feeling faded.
The poem is titled "kin," a word that suggests family or close belonging. Set beside that title, the line feels colder. A day that once might have marked a bond has gone empty. The word "anymore" matters most: it tells us the day did mean something once, so what we're reading is a loss, not simple indifference.
The mood is flat, quiet, and a little sad. The speaker doesn't sound angry or dramatic, and that calm may be the point. Judging by the tone, the numbness could be a way of protecting themselves, or it could be the plain truth. The poem leaves us to decide.
