Today was the day! He saw Chloe standing near the exit, her familiar red hair catching the light. He hurried towards her, his stride long and easy. A huge grin split his face.

She looked up, her expression guarded. "Excuse me?" she replied, taking a step back.

His grin wavered slightly. "It's Leo! From the beach? We built a sandcastle kingdom and almost got swept away by the tide?" His voice cracked slightly. His shoulders sagged.
