Just two days ago, I posted here of remembering a photo that I had taken 6 years ago. Some commented that it was indicative of good memory, which is the opposite of what I often post about, for I am also a forgetful sort of chap.
In this case, not only did I remember the old photo, but I also recognized that it must be the same lady that we had just seen again in the present. I made the connection even though we hadn't met and spoken back then, for I had photographed her rather surreptitiously from a distance.
Here ↓ it is again for reference.
