Around here a little brother is good for dressing up, serving tea, playing chase, hugging, and laughing until you fall to the floor.
He thinks he's the lucky one, but really she's the lucky one. She was blessed with a brother who adores her and does most things on command for her. But don't be fooled, he is pretty lucky himself. She loves him and plays with him when he really is getting on her last nerve.
In reality, I guess I'm the lucky one...
