We're through.

I receive a lot of peoples photographs, many of them not terribly noteworthy. These stood out because they were framed, and disposed of together without any effort to spare the photographs from going god-knows-where to god-knows-who (turns out it was me and I have no problem sharing things that are donated for eventual public sale).

 A loving couple, throughout many stages. Smoochin', looking sweetly at eachother. A presumed age difference. A smug look, potentially due to concern over the angle of a selfie. These are intimate shots.
Their donation is telling. A relationship has to end for someone to get rid of these all at once, all in once piece. 

Which is why I wonder about this one...

...is this a beloved family pet? Well, if it was, and if the pet had passed on, you would think the owner would have made some effort to retain the pictures. Maybe in a little box somewhere.
It would be one thing if this was a beloved family pet who passed on and this picture frame was too much to look at every day. The sensible thing would be to take it down and store the pictures away somewhere until the heartache fades.
For this reason, I prefer to think that this dog did something unforgivable, and that the owners were simply so disgusted with it that they never wanted to see it's face again. Maybe it was secretly selling off it's dog treats to feed a nasty gambling habit. I dunno, anything. Some sort of betrayal would explain the need to ensure that it's every image would be cast off, never to be seen again.
