A short poem by the former poet laureate Cecil Day Lewis. I have heard it used for a man with 'her' read as 'his' and 'she' as 'he'.
Her laughter was better than birds in the morning,
Her smile turned the edge of the wind,
Her memory disarms death and charms the surly grave.
Early she went to bed, too early we
Saw her light put out; yet we could not grieve
More than a little while,
For she lives in the earth around us, laughs from the sky.
