It's hard to explain the cultural and linguistic diversity you find in Ann Arbor, which is only about 115,000 people (not counting the transient undergrads) to someone who hasn't lived here. I know, I've tried. But let me show it this way:
Of the first six groups of people who were having conversations when I passed them, five of were speaking languages other than English. It was remarkable enough that I started paying more attention. By the end of my 30 minute walk, I had passed by 22 conversations, nine of them were in languages other than English. And most of them were different languages from one another.
I love it.
And I've missed it while living in other cities in the Midwest. Chicago, Kalamazoo, rural Indiana college towns, small northern Michigan towns. It's good to be back.
