Write a summary to the following  passage. Give a  suitable title to it .

A wolf came upon a lamb straying from the flock , and felt some compunction  about taking the life of so helpless a  creature without some plausible excuse ;  so he cast about for a grievance and said at last , “ Last year , sirrah ,you grossly insulted me.  That is impossible , sir “, bleated the lamb, “for I wasn’t born them. Well retorted the wolf , you feed in my pastures . That can not be , “ replied the lamb , “ for I have never yet tasted grass “ “ you drink from my spring, then , “ continued  the wolf . “ Indeed sir , said the poor lamb. I have never yet  drunk  anything  but my mother’s milk . “ well , anyhow , “ said  the wolf , “ I’ m not going without my dinner  “: and he sprang upon the lamb and devoured it without more ado.
