A few days ago, Japan Prime Minister Mori was given some basic conversation training in English before he visited Washington and met US President Barack Obama.
The instructor said to Mori, "When you shake hand with US President Obama, please say 'how are you. Then Mr Obama should say, 'I am fine, and you?'.
Now, you should say 'me too'. Afterwards we, the translators, will do the work for you."
It looks quite simple, but the truth is:-
When Mori met Obama , he mistakenly said "Who are you?" (Instead of 'How are you?).
Mr Obama was a bit shocked but still managed to react with humor:"Well, I'm Michelle's husband, ha-ha."
Then Mr Mori replied, "me too, ha-ha."
Then there was a long silence in the meeting room.
