One step forward, two steps back

Last month our power bill was double it's normal size and we've been keeping the house at 82 degrees to try and lower it this month. Much suffering and complaining going on. But it was for the greater good. Now, two days ago we came home from dinner and game night at a friends house and heard water running. After checking all the toilets and faucets inside, I realized it was the hose out back. The kids had been playing in the water before we left and they didn't turn the hose off. It had been running for 5 hours! Not just a little trickle, mind you, but almost full blast. I was so livid I couldn't even speak.
