Poem by Unknown - "Thoughts of a Blood Donor"

I gave my blood.
    Christ gave His
I gave a pint;
    Christ gave ALL.
The needle is small and sharp,
    The nails were large and dull.
The table soft and relaxful,
    The cross rough and painful.
The nurses kind and gentle,
    The soldiers cruel and mean.
The crowd applauds my sacrifice,
    They that passed by reviled Him.
Mine is for O positive,
    His for positively all.
Mine at best will prolong life for a while,
    His, without doubt, can save FOREVER.
