I remember visiting a gun show year, and a vendor had a WW2 era pictorial book on the table among others that seemed to offer pics I had never seen before. I picked it up to flip thru and see sincerely if I was interested in purchasing.
The person at the stall said the books were not for reading, I replied, "and evidently not for sale".

MY MO, "smart people know the rules, wise people know when to break them".

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
