Interesting? I almost bought a $5.99 'book of secrets' in Toy-R-Us for my 8
year old daughters birthday. She writes her secrets in the little pink book
then closes a tacky plastic lock and utters a magic word. Thereafter it uses
some primitive speech recognition to ensure Mom, Dad and brothers can't
access the secrets. Fine I thought until it goes wrong.

Bad enough for my daughter to lose access to her secrets but think of the
chaos if my wife were to lose access to her credit cards........

H'mm perhaps this is a smart idea after all!!!
