six o'clock
`` Hallo , Mr. Walmsley . Found your way back at last , have you ? Sorry I could n't bring in the automobile for you , but dad 's bull-tonguing the ten-acre clover patch with it to-day . Guess you 'll excuse my not wearing a dress suit over to meet you -- it ai n't six o'clock yet , you know . '' `` I 'm glad to see you , Tom , '' said Robert , grasping his brother 's hand . `` Yes , I 've found my way at last . You 've a right to say ` at last . '
