people said : oh , you ca n't trust 'em , trolls are ok if you 've got 'em in front of you , and some of 'em are decent enough in their way , but they 're cowardly and stupid , and as for dwarfs , well , they 're greedy and devious devils , all right , fair enough , sometimes you meet one of the clever little sods that 's not too bad , but overall they 're no better'n trolls , in fact- -they 're just like us .
