When Jerusalem converted the old British train tracks in the south of the city into a walkway/running path (akin to New York’s High Line), I started running there. And if I headed towards Beit Tzafafa, the closest Arab neighborhood, I would pass Arab couples walking hand in hand, and Arab women in traditional headdress with iPods and earbuds, jogging as well. We came to recognize each other. Still, we didn’t actually talk, but first we nodded, then some of us smiled.
