I begin to believe native English speaker
Since I have reviewed the notebook entries written by non-native Chinese speaker on italki.com , I have begun to believe native English speaker (not sure what you are trying to say). Why? Though these entries were edited by more than one native Chinese speaker, there are some words or sentences that are not appropriate or correct. So, I have decided to not read the non-native English speaker notebook entries to avoid reading wrong answers.
Did I make the right decision ?
