So here's what we learnt at Twinkle's star-studded book launch last evening. Karan Johar observes Karva Chauth. He went to the same boarding school as Twinkle. When he was particularly miserable there, his best friend Twinkle encouraged him to run away by rolling down a hill. "They caught me of course," said KJO, who obviously has forgiven the debuting author enough to have agreed to moderate at her book launch. "But of course I was made to stand in front of the assembly as a guinea pig."
