I have this Vietnamese friend well I am not so sure if its friend but we are not enemies, she is consider smart I guess, I am not so sure but sometimes she pisses me off anyways I am not going to say much about her, but she can really write good essay paper and one of my English teaher assigned us to write a story blah blah blah and she read her, it was quite astonishing. But when she is speaking she has an accent and her grammer is quite out of place. I guess some people are better to express their English on paper than the way they present it. And it is her own writing. I read some of her essays and its her, she didn't copy and paste. LOL
Well, we can't determine by the way they write. Sometimes I would do the same when chatting or writing. u noe like this. LOL that is not a good example but yeah.
