Traveling alone takes its toll. Eating alone, walking alone, drifting through wandering conversations with cab drivers—it all surmounts to what can only be described as a profound sense of isolation. No surprise, then, when a simple email or text from a friend feels like the most heartwarming hug. So thank you, friends. Thanks for the small gestures, from the one-word texts to ricocheting discussions. Thanks for being there. Thanks for the hugs.
