After the Football match, a player went home with a sorrowful face.

His surprised wife asked:

- Why are you so sad? What's the matter? He answered sadly:

- Today I got a Yellow card.

- So, did you want to get it?

- Of course not. The wife was upset:

- If you didn't want to get it why didn't you refuse it? But you did accept it, so now you are sad.
