How good can my English get there? ,F: You see how well I am doing. I studied there, too. ,M: Alright. I'll tell my father about it.

I mean, the people I worked with, very friendly and very helpful. ,M: Did you travel a lot there? ,F: No, we were very busy trying to finish the first part before Christmas.

Input: Consider Input: F: Professor Edward, could I have a talk with you about the oral presentation? ,M: OK.

In fact, it's because I'll get very nervous in front of people. It's a problem I've had since I was a child. ,M: I see. There has to be some way we can deal with it. ,F: I could write a paper instead. Some of my teachers in high school let me do that. ,M: But if I let you do that, I'd be opening myself up to the blame of unfair treatment. Well, would you be nervous if you gave the presentation in front of a video camera?
