Drriving at Bagdogra airport in the afternoon, I'm greeted by hot and humid air. "Dad, it is hot," my son complains, and before I can give an excuse, his eyes are glued to his phone. My wife's idea of convincing me to take him along on this trip to the Sikkim Literature Festival seems like a daunting task now. How do I keep a restless teenager engaged in this land's rich history and heritage?
