Here you will find the Poem A Mood of poet Thomas Bailey Aldrich
A blight, a gloom, I know not what, has crept upon my gladness-- Some vague, remote ancestral touch of sorrow, or of madness; A fear that is not fear, a pain that has not pain's insistence; A sense of longing, or of loss, in some foregone exsistence; A subtle hurt that never pen has writ nor tongue has spoken-- Such hurt perchance as Nature feels wen a blossomed bough is broken.
