I trained from an American engineer who is working in the Network security field for 2 days at my company's meeting room.
His company is my company's partner.
You can see one woman next to him. She is a simultaneous interpreter.
Her interpretation is very very great . So, I asked her at the break time,
'Did u study English in America ? '
She said, ' I have never been in America'
I couldn't believe that.
So, I asked her again, ' So, How did u study English ? Can you tell me your know-how ? '
She said, ' I can't tell it ' and then she smiled.
I envy her so much. Because I also wanna speak English well like her.
But it is not easy to me.

I think she had an American YOBO! (lover)

Good luck on following her method in Gwangju!

Im not sure that but she said, 'I took a postgraduate course and took a lot of English training course and then I traveled a lot of country.'

By the way , I tried to talk with the American engineer in my poor English.
Actually, I picked him up at the airport before Korean interpreter come here.
I asked a lot of things to the American engineer in my poor English.
But he understood what I say. So, Im very happy.
I asked one, 'what do u think of America's Iraq attack ? '
So, he said, ' It is act so silly '
