exhausted battery?

I caught ONE picture of the wonderful sky as I left work ..and than got a warning - exhausted battery! but, but, but.. what about all the other things I wanted to capture? the other clouds? the green, green of the walking path? the red tipped trees against the gray clouds? the bright yellow and lovely blue flowers at Rachelsmom's?

Leanne's "birdie" today out classed me totally anyway! one month to my next grandma time.. how many minutes?
