Try Not Biting The Hand That Feeds You.
A GARDENER’S Dog, frisking about the brink of a well in the garden, happened to fall into it. The Gardener very readily ran to his assistance; but as he was endeavouring to help him out, the cur bit him by the hand. The man took this ungrateful treatment so unkindly, the he left him to shift for himself, with this expostulation; Wicked wretch, quoth he, are you so unreasonable as to injure the hand that comes to save your life! the hand of me, your master, who have hitherto fed and taken care of you! Die, as you deserve; for so mischievous and ill-natured a creature is not fit to live.
