The twins came into the house yesterday, saying they thought the neighbor's property was on fire because there was a lot of smoke.
Chris went out and looked and they all came back into the house explaining that they are probably having a big bonfire to get rid of things they don't want around their property, just like we do.
A few minutes later, a fire truck came down the street - so Chris revised his thoughts to, "Well maybe they do need help! Let's go see. Where's the camera?"
