Agree. Common sense and non sense are relative! Kind of like my favorite saying that "I" coined:
"Insanity is just a state of mind."... you've really got to think about that? If the majority of people were "insane" that would be considered "normal" and "normal would be "insane". So who determines what is really "normal" and what is "insane"? It's relative .... a 'state of mind?" who's mind?
So is common-sense and non-sense. To one common-sense is non-sense, and to the other non-sense is really "common"-sense!
I think my head is splitting over this one! :)
