Hi,
Before laughing at others', check your own mistakes first. I don't think there was anything wrong with Nan-nan. Don't forget she was a student. She had the courage to defend her boy friend by using her limited language skills. If anybody's fault, that's Gary's. In China, "Once a teacher, always a teacher". That means he had the responsibility of correcting her mistakes in the process of learning. While some of you were mocking her for her mistakes, had you ever re-read your own writing? To be quite frankly speaking, among most of the post in the forum, lots of mistakes were treated as typing errors. I believe we all understand. Students need encouragements, not mockery.
