Famous quotes containing the word service:

    “We too are ashes as we watch and hear
    The psalm, the sorrow, and the simple praise
    Of one whose promised thoughts of other days
    Were such as ours, but now wholly destroyed,
    The service record of his youth wiped out,
    His dream dispersed by shot, must disappear.”
    —Karl Shapiro (b. 1913)
