You sigh heavily as you flop onto the couch in the common room of a hostel, where you will be spending the next few days of your journey. You scroll through the photos you've taken so far today when out of nowhere, a stranger places a plate of freshly baked cookies and a steaming cup of tea right in front of you. "You look malnourished," he says with a glance. "Have you even eaten today? Eat, someone needs to look after your basic needs." His German accent is distinctly audible.
