Waiting on a Moment

My family and I recently went to the zoo, and of course, my camera was hanging on my neck. I walked around the park snapping shots most of the day.. flowers, trees, and of course the animals. Early on in the visit I walked past a bush of flowers and a beautiful little Monarch butterfly fluttered in front of me and landed on the flowers. I stopped, walked as carefully as I could toward it and scrambled to get my camera on.. just as the camera came on.. my little friend flew away. I turned and watched as it dipped and dove and fluttered across the path I was on and over to another bush on the other side. I watched as it danced on the breeze and silently floated away. I was disappointed. I wanted a picture of that butterfly.
Throughout the day I kept seeing butterflies... more Monarchs as well as Yellow Swallowtails. The dance was the same.. they'd flutter in front of me, tempting me with their beauty.. and continue on their merry little way. Sigh...
Why was it that the shot I wanted, wasn't of an animal in a cage that had no choice but remain in front of me, but of a tiny little creature that roams free?
At the very end of our day we were walking towards the exit and once again a little butterfly dipped in front of me. I stopped and watched where it was going. It dipped and dove and bounced about around me and without thinking, I pleaded: "Please, Little Butterfly... Come on!... Please land.." And it did. It floated over to some ferns and came to rest for me. He didn't just stop for a second, he spread his wings wide for me to see his beautiful markings. I had been waiting on a moment like this all day long. I had my camera on this time and crept up as close as I could... I zoomed in and snapped three quick shots...just before my camera shut off from an exhausted battery!
