You can't do anything about the past. And you don't know what the future is.
The pictures remind you of something that can never be recaptured, the time is gone, the only thing you know is the present. That's all that's knowable and even the present isn't knowable. The present becomes the past... so you really don't know anything.
I love cameras but I find myself reluctantly taking pictures because what's past is past.
We're all embers from the same fire. Our ember winks out, we're ashes, we go back to the fire. I like that image. There has to be a unifying theory. I think there is a continuity of some kind, that my love for my wife will go on past the death of my body. Nature is perfect.
