Sarcasm isn’t a right, is it? It is a privilege to be earned. Earned through building a relationship of respect. Then, once in a while being able to go off on a limb and throw in a bit of a sarcastic remark just to get the conversation going, create a small laugh, or catch someone from going down a path they should not wander (conversationally speaking).
So, Sarcasm isn’t a right. It is an earned privilege, yet… still should be used sparingly.
