From Walking with Abel: Journeys with the Nomads of the African Savannah by Anna Badkhen:
We walk into one another’s lives, we change them and are changed deeply and forever, we part ways. Each time a part of our hearts seems to shrivel and die, it doesn’t. Simply, our hearts learn to beat a different way. We mourn, we break down, then we stand up, and we keep going. Two thousand footsteps per mile. Twenty to forty thousand footsteps per day. Every footfall brings the walkers closer to a reunion. Every footfall begets a separation. Our forward movement, erratic, fragile, relentless, is a quest: for comfort, for deliverance, for squaring the ideal of endurance with the practice of love.
