There are little snowflakes dancing down from the clouds in time with this song playing in the background. One of those perfect moments when sight and sound meld together in beauty clear enough to make you gasp with wonder.
I believe this to be "the flash" dear Emily wrote about.
I understand why it would be called "the flash" as it was gone in an instant overtaken by multiple people and timers and needs all suddenly so urgent to everyone else. Me, I just wanted to continue to stare out the window and hope the song would never end.
