That is a photo(shopped) of an actual diner in the community I grew up in. It was called the “Mountain House,” and I waitressed there from time to time as a young adult.
I don’t much care for waitressing. I think there are more cheerful, friendlier people who would do a much better job. I am content to build web sites.
See the cross on Sparrow? I never got into it very much, but Sparrow considers herself a good Christian. She goes to church, etc. I had a story where her mother turned out to be a huge hippy, and this was Sparrow’s way of rebelling. But I never had the chance to write it!
