I lived there 20 years and knew the post lady very well

I was in an old, historic, small town and it just had a post office, a cash-only restaurant, and a convenience store at its center. When I was working to lose some weight, I would walk to the convenience store each day and buy 1 canned or boxed item and I saved up a weeks' worth, copied the "weight" of each and added them up (almost 5 pounds) then mailed them off to a food bank and determined to lose that amount of my own weight by the end of the month.

I love thinking up odd little experiments and projects like that. On one of my walks with my postcards, I found a bunch of pennies scattered in the road! I collected all I could find and there were 9 of them. So, I made up a short story about "searching for the tenth penny" Every day as I was walking to the post office, I'd think up different endings (what if I were to be bold enough to ask the next person I saw if they had a penny I could have; what if I were to start collecting found pennies, walking/searching until I found 100? :-)
