Snow Patrol - "Chasing Cars"

Our string of songs featured on Grey's Anatomy continues with Snow Patrol's "Chasing Cars."  The catchy song never quite gets out of neutral, but somehow still works.  I remember this song playing in the background as my then-girlfriend told me that she decided to move to Africa (who moves to Africa?!?).  How does one respond to a statement like that?  I believe stunned silence was my response allowing my brain to capture the lyrics to this song.  Years from now, I wonder if my brain will trigger that same flood of feelings.
