INGRATE, n.
One who receives a benefit from another, or is otherwise an object of charity.
"All men are ingrates," sneered the cynic. "Nay," The good philanthropist replied; "I did great service to a man one day Who never since has cursed me to repay, Nor vilified."
"Ho!" cried the cynic, "lead me to him straight-- With veneration I am overcome, And fain would have his blessing." "Sad your fate-- He cannot bless you, for AI grieve to state This man is dumb."
