There is a strange job out there: the florist. Its definition is “a person that arranges and sells cut flowers”. The latter part is okay, but in this case florists would be flower vendors.
The only reason why florists have kept their jobs and not become artists is symbolisms. Apparently different combinations convey different meanings, so florists need to make sure I won’t offend the person I’m giving the flowers to. But the only people who know these meanings are, well, florists. Madness.
Florists should just make beautiful flower combinations, therefore becoming artists.
