Why do you take photos?

I like to take photos of things.
Some day the things that I take photos of will be gone.
Some things will be gone sooner than other things.
Somethings just change slightly.
Other things are removed completely from existence.
As though they had never even existed.
With a little luck the photo will always mark that thing into that place and that time, forever.
That in itself is a good reason to take a photo.
