no,no,no,no,no. a thousand times no.

let me tell you what you're doing when you use the feedback sandwich. you are patronizing, and you will be hated. this article has everything wrong and you shouldn't even read it.

ALL you need to know about criticism is to never, ever give criticism. The reason is because its lazy and it shows you don't care.

If its absolutely critical that bad behaviour stop immediately then demonstrate the(or a) right way to do it. This shows you care. if it isn't received with a positive response then the person doesn't understand or believe there was a problem. Now you can bring out just enough factual information to impress that the issue is real. then immediately apologize for not telling them sooner.

title of the original article should be, "how to be a passive-aggressive troll"
