A singing Robin was chided by a Sparrow at his poor song. Robin replied that other birds were not around and he was doing his humble best.
There will always be a critic no matter how hard you try.
As a Redbreast was singing on a tree by the side of a rural cottage, a Sparrow, perched upon the thatch, took occasion thus to reprimand him: “And dost thou,” said he, “with thy dull autumnal note, presume to emulate the birds of spring? Can thy weak warblings pretend to vie with the sprightly accent of the thrush and the blackbird, with the various melody of the lark or nightingale, whom other birds, far thy superiors, have been long content to admire in silence.” “Judge with candour, at least,” replied the Robin, “nor impute those efforts to ambition solely which may sometimes flow from love of the art. I reverence, indeed, but by no means envy the birds whose fame has stood the test of ages. Their songs have charmed both hill and dale, but their season is past and their throats are silent. I feel not, however, the ambition to surpass or equal them; my efforts are of a much humbler nature; and I may surely hope for pardon, while I endeavour to cheer those forsaken valleys by an attempt to imitate the strains I love.”
