When I was 6 we lived on a farm and had the Monday to Saturday newspaper delivered to our door. (The morning bus driver would throw it out when he went past, then the dog would find it and bring it the rest of the way).
When I was 6½, they introduced a Sunday edition, parents did not want to order it sight unseen, so that first Sunday, I walked one mile to the township by myself to buy a copy.
Nice story, but I suspect they are not living in rural area. 1 Mile out in the sticks is a far cry from 1 mile in a city. I walked long distances too when I was young, but I grew up in a more rural area, I think 1/2 mile is a bit far for a 6 or 7 year old these days in an urban environment these days sadly.
