re: Marking yourself safe on Facebook... the height of narcissism

Marking yourself "safe" has the same goal as all the idiots who post endless selfies everyday. They are people with low self esteem and are fishing for compliments, so that they can feel better about themselves.

Bill Engvall had a whole routine about "Here's your sign", implying stupid people should carry a sign letting everyone know up front. This is just an extension of that.
