Suddenly, he saw her, across the dance floor. It was Emily, his ex. He felt a sudden jolt. A feeling of… anticipation? He adjusted his suit jacket, feeling a grin spread across his face.

She turned, her eyes widening in surprise, then quickly softening. "Michael! I didn't expect to see you here!"

They fell into easy conversation, and before the night was over, they danced the night away.
