From one big sister to another

We have some friends at our church who were pregnant with their third child.  Their other two children are 4 and 8.  Their 8 year old daughter is in class with the Genius.  Our friends had their daughter a few days ago.  Their 8 year old daughter was excitedly telling the Genius that she was a big sister again and how neat it was.  The Genius told her, "Well enjoy it. They grow up SO fast!"  LOL!
