In explanation of the entry Spring becomes Summer, I am attempting something known as Haibun, a Japanese form of writing that combines short (usually) prose and Haiku. As with all Haiku, the symbology used is very important. In the case of Haibun, the symbology can be directly related to the prose, purely symbolic, or have some personal meaning to the writer.
Haibun, like Haiku, makes extensive use of kigo, which is symbology tied intimately with the seasons. While mirroring nature in some way, the seasonal grace of a Haiku or Haibun is based not only on a reflection of nature but also the symbology. Old is winter while Young is Spring.
