Then we would know that this bouquet:
has white hydrangeas in it, and hydrangeas mean frigidness or heartlessness. We would also know that this sunny little bouquet in a pot:
contains marigold, statice and aconite, which mean, respectively: pain and grief, remembrance, and misanthropy. So what looks to be a happy, bright bunch of flowers actually tells the sad, sad story of a photographer whose cat got hit by a car and now he hates everyone. Except people don't speak the language of flowers anymore, so the photographer's message, cleverly disguised as a stock photo of a very yellow backdrop and quite a lot of happy yellow flowers, remained unnoticed.
