Something I Can't Live Without . . . . .

. . . . . light & water. They're life-bringing.
The more I've been involved in photography, the more and more aware of 'light' I've become; the magic that's created as the light changes!
And 'water' changes everything too, bringing life and hope. I guess that 'light' does the same thing. 
The challenge for MonoMonday is 'Something I can't live without'.
