Oh my gosh, it not so cool to stress myself for  those people who are bitter in their life. As much as possible i don't want to stress myself on this small issue in my work. I' ve already admitted that i did something wrong but it was not my intension that the word i used was misinterpreted on her side. so lesson learn we can't please everyone even  how we try hard to understand them there are still people who are so full of in their life so all we have to do is DON'T TRY.
