My Sassy girl is quite the social butterfly. She'll strike up a conversation with anyone and tell them her entire life story, real and imagined. A lot of adults don't quite know what to make of her.
Yesterday we went to the local Shakespeare festival for one of their children's performances, put on by a troupe of college theatre majors. When it was over, the actors lined up in the back to talk to the kids. Sassy marched up to them and said, "Hi, my name is Sassy, and this is my invisible friend Linda, and today is Linda's birthday." Without missing a beat, they all turned to the empty space next to her and said, "Happy birthday, Linda!" It made her day, and mine.
