Input:  Person1:     What should I get Uncle Teddy ? 
 Person2:  You could get him a tie . 
 Person1:      Are you kidding ? That's the stupidest gift one can buy . I don't want to get a tie . 
 Person2:  Why not ? 
 Person1:      Everybody gets men ties for Christmas . It's too boring . Everybody buys either ties or sweaters . I want a more unique gift . 
 Person2:  Well , you can buy him a pet iguana then . 
 Person1:      That's a cool idea . At least it would be a surprise.But I'm afraid he wouldn't take care of it . 
 Person2:  He would think you were crazy , Caroline . 
 Person1:      Yes . An iguana is too strange for a gift , and a tie is too normal.So I have to find something halfway between . 
 Person2:  How much do you want to spend ? 
 Person1:      Well , he was very good to me.He helped me edit my essay for the scholarship contest.So I want to spend at least 75 dollars . 
 Person2:  Alright , I have an idea.You know he carries that conservative-looking briefcase every day . 
 Person1:      Yes . 
 Person2:  Well , he isn't a lawyer , so I don't think he needs to have a briefcase like that . 
 Person1:      What should he have then ? 
 Person2:  I think he would appreciate having a very fine leather bag.But more like a workbag or shoulder bag.You know , not so hard and square like a briefcase . 
 Person1:      I think that's a great idea . Men look great with that kind of bag.Where can we buy one ? 
 Person2:  I don't think this mall has a leather goods store.So we have to go to State Street . 
 Person1:      Alright . We can go later then . 
 Person2:  We can buy something for Mom and Dad here , and then go buy Uncle Teddy's gift on State Street . 
 Person1:      Good plan . What should we get for Mom though ? 
 Person2:  She said she wants one of those automatic foot massagers . I think they sell them at Sears . 
 Person1:      Alright . We can go check at Sears and see if they have them.And what about Dad ? 
 Person2:  How about the iguana ? 
 Person1:      I think it would be a great joke.But I know we'd have to take the iguana back . And the pet store might not let us.So why don't we get him something else ? Some clothes maybe . 
 Person2:  A tie ? 
 Person1:      Oh , shut up about ties ! Forget about ties , why not ? 
 Person2:  I was just kidding .
