After working one too many storms, Rainbow Dash comes down with the flu. Her sister, Applejack, knowing all too well that her sister will continue playing in the rain when she is sick, insists that she stay at Sweet Apple Acres until she is better. Apple Bloom wants to make her feel better so she makes her sister some vegetable soup

Short sisterly fluff that takes place before Friendship is Magic in the universe of the "Believe" series. Read "Give to Good Home" & "Sisters of Different Blood" if you want to get a better picture of how this story fits in but it is not necessary for enjoyment of story.
