One of the important lessons that Harold Fry learns is that he’s not the only one with problems, that he has much in common with the people he meets.
In The Unlikely Pilgrimage of Harold Fry, Rachel Joyce writes, “People were buying milk, or filling their cars with petrol, or even posting letters. And what no one else knew was the appalling weight of the thing they were carrying inside. The inhuman effort it took sometimes to be normal, and a part of things that appeared both easy and everyday. The loneliness of that.”
