We all have our own phrases. Sometimes we don't know where they cone from. I always tell the kids to "pick up the floor" meaning to pick everything up off the floor. I don't know why I say it this way. The kids always make a comment about it.
Today we are clearing out the house. We have a dumpster. There us lots of floor to pick up :)
SW walked into the living room and says "Mom, I finally picked up the floor.". :)
