Under the glassy smooth surface,
roughness grabs the eye.
While haiku usually have 3 lines, some haiku do have just 2 lines. For example, Santoka Taneda (1882-1940) wrote a number of 2-line haiku.
After writing my first 2-line haiku, I reworked it to be a 3-line haiku that I preferred. I posted both and found that a few readers preferred the original 2-line version.
The haiku in this post is my second 2-line haiku, reworked from one with 3 lines. It is probably safe to say that it will stay at 2 lines, but don’t place a heavy bet.
