The river meanders

The river has tributaries. Likewise, my young man leaves his hometown and me, he returns, he leaves again, and he doesn’t take me with him. Small islets of the river disappear when the river rises. Likewise, he returns, he doesn’t remember me, he leaves, and I am left alone. The river changes course. Likewise, my lover returns and he doesn’t come see me or think of me at all, and both of us sing a sad song.
