hey，jim。what i understand form the picture is that i think that it is worry of longer pencil laugh at shorter pencil，because it is obvious that shorter pencil used to be used by someone，so，he must have made some works，it is these works that he reflects his value from。however longer pencil haven't done some works，（he has a long of way to walk），so i hope that longer pencil should be hard to learn the experience from shorter pencil than to laugh at shorter pencil
