I wish, I wish upon a star...

Many children's wishes start out like that. However, young Starlight Glimmer doesn't believe in wishes, and her best friend, Sunburst, wants to try it out. But when humiliated for one final time, Sunburst leaves her during a meteor shower, and in a last ditch attempt to keep their friendship in tact, wishes that their friendship will last throughout whatever hardship came their way.
