`` The motion is put and carried , '' put in Dick just as promptly . `` I trust , though , the concert do n't make us weep . '' `` They wo n't know we 're there , so perhaps they wo n't try it on too hard , '' said Sam , and there the students ' slang came to an end for the time being . The concert was quite to their taste , and they were surprised , when it was over , to learn that it was after eleven o'clock . `` I had n't any idea it was so late , '' exclaimed Dick . `` We 'd better be getting back to the hotel , or we wo n't get our money 's worth out of that room . '' `` That 's right , '' laughed Tom .
