Input:  Person1:     Tonight is a party night ! What drinks do you think we need ?  
 Person2:  Well , not everyone wants to drink beer . Make sure there are some soft drinks and juice . Nothing's as refreshing as iced drinks on a hot day .  
 Person1:      I don't think we need too much in the way of soft drinks , Two super bottles of Cola should cover everyone . What about wine ?  
 Person2:  Just buy a cask of wine . Have you bought ice yet ?  
 Person1:      No , once I fill the tub with beer , I'll get the ice . The beer will be cool if you put the tub under the ice . The cooler , the better .  
 Person2:  I think a bottle of champagne would be a good idea . It's appetizing and tasty .  
 Person1:      Well , if you say so . Personally speaking , I'd rather die of thirst than drink champagne .
