My grandmother was a kind, sweet and gentle person. If someone hurt her, she never hurt them back. Her only act of retribution was to cut them out of photographs, a bit like the way that ancient Egyptian rulers would have images of their disapproved-of ancestors defaced. She also cut herself out of photos if she didn't like the expression she was pulling.
I don't know who was third from the left on the back row, but they did something to offend my grandmother so off they went.
I don't think there was a bad dog at the front there, that's just a regular tear....
