Two short lines carry a lot here. The speaker says they let "him" go "to the way he want," which reads as allowing someone to follow his own path, even if that path leads away. The title, "kin," suggests this person may be family, though the poem never says so directly. If he is, the distance matters more.
The second line is a question: "am i supposed to be sad ?" The speaker doesn't announce grief or relief. Instead they seem to check their own feelings against what others might expect. That small gap between what they feel and what they think they should feel is the heart of the poem.
The mood is quiet, flat, and a little guarded. The lack of capital letters and the plain, slightly broken grammar make the voice sound casual, almost shrugging. But the question hints at something underneath. Maybe the speaker is numb, maybe they're truly at peace, or maybe they're hiding hurt. The poem leaves that open, and that uncertainty is what lingers.
