„It was sweet, my love, a while
To live our life beneath the grove of birch,
More sweet was it fondly to embrace
Together hid in our woodland retreat,
Together to be wandering on the ocean's shore,
Together lingering by the forest's edge,
Together to plant birches – task of joy –
Together weave fair plumage of the trees,
Together talk of love with my slim girl,
Together gaze on solitary fields.“
