Venn Diagram Poem

     One of my granddaughters has been working with Venn diagrams in her middle school math class.  And my thoughts turned to this poem -- back in 2018, Twitter poet Brian Bilston (@brian_bilston) celebrated the August 4 birthday of the diagram's inventor, logician John Venn (1834-1923), with this clever poem in a Venn diagram.

Lots more of Brian's poetry adventures can be found here at his website.
