you are right

One day Juha was being a  Judge in this town
a few days later ,Two persons came to him. The first clarified this problem and explained  his point of view convincingly. At the end Juha said:
  -You are right! I agree with you
 in this time the second person came and explained everything convincingly from his point of view. At the end Juha said: 
You are right! I agree with you.
 but  Juha's wife was beside him and said: Juha! what's this, it's impossible, and They can't both be right. 
 Juha turned to his wife and said :  ok my wife . You are right also.....
