When I was in second and third grade, I knew of a secluded spot, a pond, where I could find empty coke bottles. There were many days when I gathered them up and brought them to the store for money. It wasn’t until many years later that it occurred to me that back in the sixties, that some girls used coke as a douche. Just hold your thumb over the top and shake it. I wonder if any of the soda bottles I picked up were used for that purpose.
