It was her last breakfast with Bapi, her last morning in Greece. In her frenetic bliss that kept her up till dawn, she’d scripted a whole conversation in Greek for her and Bapi to have as their grand finale of the summer. Now she looked at him contentedly munching on his Rice Krispies, waiting for the right juncture for launchtime.He looked up at her briefly and smiled, and she realized something important. This was how they both liked it. Though most people felt bonded by conversation, Lena and Bapi were two of a kind who didn’t. They bonded by the routine of just eating cereal together.She promptly forgot her script and went back to her cereal.At one point, when she was down to just milk, Bapi reached over and put his hand on hers. ‘You’re my girl,’ he said.And Lena knew she was.
