Chalk and cheese

The tour guide at Dublin’s Farmleigh House used the expression “chalk and cheese.”

I took it to mean something like “apples and oranges,” “two things you can’t compare.”

Or maybe it’s more like, “two things that are very different but which you could mistake for each other.”

Went looking for real life examples and found this fine, civil exchange on a Linkedin story about Lagos and Tokyo, whether they are chalk and cheese:

Interesting point about Tokyo’s 23 wards!  Sometimes I wonder if Los Angeles needs way localer governance.
