Have to say i enjoyed today’s Frazz. It gets both points across well.
However, According to a Japanese exchange student I once taught, haiku is built on the 5-7-5 pattern and refers directly or obliquely to nature or a season of the year. Rhyming is not a requirement.
As it is a very interesting art form I also recommend Britannica at https://www.britannica.com/art/haiku and several other sites, including Wikipedia.
