Coincidence?

"So what are you going to play for us?" A lady asked me as I stood between her and her neighbor's bed.

I thought for a second. "How about a love song?" I said. The suggestion was received with warmly received by a room of women.

"All I Ask Of You" from Phantom of the Opera entered my head, and a sweet conversation between two lovers flowed from the violin. As soon as the song started, I noticed the lady who had spoken to me exchanging looks with her visitor.

"What was that song?" She asked eagerly, hardly waiting for the bow to take off from the strings. I told her the name of the song.

"I knew it! I knew it!" Her eyes shone brightly as she tapped her visitor. "That's the song my granddaughter is singing tonight at her school play! Oh boy..." she held her hand on her chest. "I was a little depressed that I would miss her play, and now, to hear it here..." she stopped for a second, looking for words but couldn't find any other than a soft "Thank you."

Of all the songs, of the rooms to play them in--how does one explain something like that? I love moments like this.
