What does it mean to be a good brother? Congress president Rahul Gandhi tried to throw some light on the matter when he bumped into his younger sister, Priyanka Gandhi Vadra, at the Kanpur airport today. "Let me tell you what it means to be a good brother, okay?" he said with his arm around a laughing Priyanka Gandhi's shoulder. "What it means is, I am doing these massive long flights, and I am going in a little helicopter like that, squeezed up, and my sister is doing short flights in a big helicopter... But I love her!"
