Another rider joins the Lyft pool. Now I might be late for my date. “Mustafa?” the new rider asks. “Yes. Melissa?” Wait a minute, I think. I’m on my way to meet a Melissa. “Melissa?” I say. “Yes?” she replies. “It’s Erik.” She doesn’t put two and two together. Awkward silence ensues. “Oh, you’re actually going to the same place,” says Mustafa. “Really? Why are you going there?” Melissa asks. “Uh, I think I’m going on a date with you,” I say. Mustafa laughs. We join in. I feel briefly hopeful that, despite apps and algorithms, serendipity still exists.
