Dog gets the last bite
This is a pretty sad story that begins with a wholesome relationship between dad and dog. The pup would always get the dad’s final bite of his sandwich. It was a ritual between the two that never needed explanation. If the dad had a breakfast sandwich, the dog was entitled to the last bite.
However, after the father had passed away, there was no one to offer it the final bite of a breakfast sandwich any longer. The OP talked about how sad it is to see the dog looking around expectantly around the breakfast table every morning for a sandwich that was not coming and would never come ever again.
