Hakkai no renga is Japanese collaborative poetry, consisting of a haiku form stanza (lines of 5-7-5 syllables) followed by a stanza of two lines with seven syllables each, repeated: 575-77-575-77, etc.
Posts here have these “renga” appended as comments. Please feel free to add either a 575 or a 77 as appropriate. Succeeding stanzas should somehow fit, though “fit” here is a highly subjective term and obliquity is not to be shunned

From Robert Hass, The Essential Haiku:

The term hakkai means “sportive or playful”. It came to be applied to a kind of Japanese poetry that originated in the middle ages or earlier, called renga. Renga was a form of collaborative poetry, usually written by three or more poets, that was created by giving the tanka, the five-line poem of of the classical anthologies, a sort of call-and-response form. One poet wrote a first verse of three lines in a five syllable-seven syllable-five syllable pattern (ed. note: these first three lines of the tanka are called hokku), and the second poet completed the tanka with two seven-syllable lines.

   life is moving oh so fast
   I can’t let fear become me

I saw yesterday morning? No, I think it was a female helmeted guineafowl, a game bird more common to Kenya than Kedzie Avenue in Chicago. It soon tired of me, and took off

in an impressive, if not conventionally graceful manner, traveling about 75 feet before running out of gas. I presume it escaped from someone’s urban ranch.
