A few more quotes! “Oh!, faint delicious spring-time violet, Thine odor like a key, Turns noiselessly in memory’s wards to let a thought of sorrow free.”-quote by William Wetmore Story! (This quote makes me think of different forms of keys !, in a literal sense !, such as if you spritz orange peel mist key into a lock then it opens up a oranges trees orchards ! if the make keys in invisible scent shapes!, or other invisible senses ! , like a perfume key combos maybe open a door ! This technology maybe already exist !, such as biometrics or holography type stuff!)(but hopefully the sweet juicy fresh windy sunny rainy oranges trees would be free for everyone all creatures too and not be locked up and not needing a fragrance key !)
