Input:  Person1:       Daddy , what's next ? What else do we do now ? 
 Person2:There is a man-made fishing pond nearby . So , What do you think of going fishing there ? 
 Person1:        Great . Let's go . Where is it ? 
 Person2:Patience , boy . A watched pot never boils . We shall get out fishing stuff first and make some baits , too . 
 Person1:        We have many cookies left here . Can we use them as baits ? 
 Person2:I don't think fish would like them . Instead , they love earth worms . 
 Person1:        So let's go and catch earth worms ! 
 Person2:OK . I think that's enough for today . Let's go . 
 Person1:        Daddy , do you think we're gonna catch any fish today ? We've been fishing here for more than two hours , and we get nothing . 
 Person2:That's because you're talking to me all the time . Be patient , or there will be no chance to have sashimi for dinner today . 
 Person1:        I love sashimi . Did mom bring any soy sauce for that ? 
 Person2:I suppose she did . Be quiet . There is a fish on the hook . Here it is . Look , a big one . 
 Person1:        Cool . Hey , I've got an idea . Why don't we cook it separately ? Half for sashimi , and the other half for grill . 
 Person2:Great idea . But the fact is we have no barbecue with us . Moreover , the sashimi will be great . So why do we bother to waste time on barbecuing the fish ? 
 Person1:        Well , all right . There is nothing to complain about .
