Sisterhooves Surprise

Scootaloo answered the door.

“Hi, Rainbow Dash!  What are we going to do today?” Scootaloo greeted eagerly.

“You are going to read this,” Rainbow Dash answered, handing Scootaloo the adoption certificate.

Scootaloo looked skeptical, but she still opened the folded piece of paper.  Once she read the first two lines, her face lit up.  She immediately jumped up and hugged Rainbow Dash.

“Thank you, thank you!  This is the best birthday gift ever!”  Scootaloo squealed.

“Anything for you, squirt.  After all, you are my little sister,” Rainbow Dash replied.
