This lady was not our guide in Sapa, but she followed us through 5 hours of strenuous hiking anyway. She followed us for miles of ascents and descents. She held my hand as I struggled to balance on steep, rocky slopes in my expensive sneakers, while she climbed easily in flimsy plastic sandals with a baby on her back. She followed us for 5 hours; all with the hope of selling us $5 worth of embroidery at the end. And then she went home to stitch more embroidery for the next day.
She smiled the whole time.
