Why does this always happen?

I was so upset!! We all loaded up Saturday morning to go to Houston/Mantee. We meaning Brian, Nathan, Jacob, William, Mari Morgan, and myself. We were crammed in the car and so I wanted to take a picture of the kids in the back. When I went to get my camera out of my purse, I noticed it was turned on. I had left it on by accident all night in my purse. It only takes one kind of rechargeable battery. Where was the extra battery? At home! Where were we? Too far to turn back around to get it. When we arrived, my mom said her camera had no film. So,unfortunately we have zero pictures of our weekend, but we sure did have fun!! This is not the first time this has happened! I'm not very good with these kinds of things!! Hey, but atleast I didn't spill coke all over it. :)
