You have kids and you need to ask that? Lol We used to have a couch that was up tight against the wall. It was a huge heavy thing and hard to move without scratching the floor so we only moved it a couple times a year. One cleaning day, we found about 50 pounds worth of candy wrappers behind it. DH's kids taught mine to do that. Not as bad as oldest DD learning to cram everything under the bed and putting the cover on so it doesn't stick out. Her friend helped her "clean."
