Input:  Person1:     So how's everything going for Christmas ?  
 Person2:  I've got all the presents I need , and my family is working together to get all the food ready . That's easy , but I have another problem to deal with .  
 Person1:      What's that ? Don't tell me you've still got Christmas cards to write , it usually takes my wife a month to write all of ours .  
 Person2:  No , I did that a long time ago . It's about telling my son the truth about Santa Claus .  
 Person1:      He still doesn't know that Santa isn't real ? How old is he , eight ?  
 Person2:  Yes . He's never said anything so I never told him . But now that he's getting older ...  
 Person1:      You think it's better that he should be told ?  
 Person2:  Yes , he's too old to believe in that type of things . And I'd rather tell him before the kids at school do .  
 Person1:      That happened to my oldest girl . She became really upset when her classmates told her Santa wasn't real .  
 Person2:  I can understand . I was lucky with my oldest , she figured it out by herself and didn't tell my son .  
 Person1:      Well , when you tell him , be gentle . It's hard for kids to find out something like that .
