The best man

I was nervous as could be, even though it wasn't my wedding. All of a sudden an arm winds in mine, and the clearest blue eyes stare down at me. His smile shines, and he leads me across the aisle. I stand beside the bride and he beside the groom. The whole room stared at the couple, but we stared at each other. There was something about him, something that I couldn't put a finger on.
