My "Saying Hello" photo albums are actually an old concept of mine being resurrected.
Many years ago when I was interested in actual photography (you know, with real cameras), I enjoyed taking time for both relaxation and exercise to occasionally walk around large cemeteries. I would often be amazed at just how old some of the tombstones were. Going back to the 1800's? Amazing.

I would literally, as in verbally, say hello and introduce myself briefly to those whose graves I chose to shoot photos of, and then thank them for allowing me to do so. I guess some of us have weird hobbies, don't we? I'm more relaxed in an old and quiet cemetery than many places, so this piece of my character gave way to what I called my "saying hello" collections.
