People are emotional. Few could handle the emotion properly when upset or over-excited, which usually exist when some abnormal events happen. Sorry a human error, click a wrong key, deleted most of words. I have introduced a lot of constructive and protective methods to write concise and helpful posts for involvement and myself, but still could not stop the human errors and upset the fragile feelings terribly times by times. However it is a risk which have very littel real consequences. Just leave it as it was and move forward to update my mind.
