Oh yes, the backpackers. Completely individually they are traveling the country with the Lonely Planet in their hand. They meet outer backpackers in the Blue Lassi Shop in Varanasi, after they have “done” the South. They tell you how amazing everything is, whom they have met and discuss peace and freedom. Yes, I am also guilty.
