Sadness
Child of mortality, whence comest thou? Why is thy countenance sad, and why are thine eyes red with weeping? Anna Letitia BarbauldHymns in Prose. XIII.
A feeling of sadness and longing, That is not akin to pain, And resembles sorrow only As the mist resembles the rain. LongfellowThe Day is Done. St. 3.
We look before and after, And pine for what is not, Our sincerest laughter With some pain is fraught: Our sweetest songs are those that tell of saddest thought. ShelleyTo a Skylark. St. 18.
