The sister I never had

I pretty much got this whole story planned out already and i really hope it touchs all your hearts. I dedicate this to my neighbor Molly.
Molly, you have left us but, we know your watching over us from up above and your dancing with angels. I miss you dearly sweet one. And this year, on June 6th, we'll celebrate your 8th birthday. We all love you Molly. never forget that
