Today Adam wanted to shake off the front door's mat because it was full of sand. So he opened the front door and *carried* it through the entire living area - first to the dining room, then kitchen, doubled back through the living room, computer nook next - and finally, finally made it to the BACK DOOR. Naturally. Because that's where I shake out the laundry room's rug.
Sometimes it can be difficult to keep up with these little people.
