"No Dark Sarcasm in The Classroom"

Sarcasm is a poison... a poison that can ruin someones reputation. It is a demoralising hit to whoever it is spoken to. I think that people should start cutting back on sarcasm simply for the reason of the devaluing nature of it it is a way to tear someone down and write it off as a "joke". This also goes for the phrase "just kidding"...you're not kidding and everyone knows it if you have to say just kidding after something you shouldn't have said it. Just cut it out that small thing and make a big impact.
