Last summer vacation, I worked in restaurant. One day, I was about to be off duty while three foreigners came in. Since it was my first time to talk with foreigner, suddenly my mind went blankly. I failed to respond to their questions. And a few minutes later, I refreshed myself. So, I began to talk to them and adapt to that atmosphere gradually. I restarted to pick up my confident again. One of them, that seemed in his thirties, praised on me for my self­confidence. After that, I swore I must learn English well, especially spoken English, and never make that embarrassing thing happening again.
