What Do You Expect ?
I remember a time when I went for a programming course. There were only 4 or 5 students in that class and one of them was a PRC.
Basically, you can't expect her to speak fluently like us in English. But, I felt that she was a bit rude when she halted the class for her own benefit. I understood her situation because she was not getting the part where it would be of help to what her job or project that required her to produce.
I think it was the frustration that she was not able to tap much from her teacher. The course was a basic one for 5 days. What to do ? For enthusiasm, yes. For project, no.
