However I do notice that you and other 4 or 5 IDs are very close friends with this cwang,as you always exchange many personal life matters to each other, especially when one of you received complain from other ID.
As an educated professional, I believe that we need to respect all IDs equaly on the website, should not bring up personal friendship to defence the one whom is from your friendship circle. When we are trying to dicuss some concerns, even friends can have disagreement,but open mind discuss will not hurt, because everyone can have more clear mind. Isn't it?
