It's time for the rope to be pulled, and the girls are ready to go. They're worried that the rope will be pulled too far, and that they'll lose their balance, which will make it impossible for them to get to the bottom of the well. They all agree that it's a good idea to go ahead and pull the rope, but they don't want to go too far because they're afraid that the rock will fall and injure them. They agree that they need more weight to get up to the top of the rock, and then they all laugh at each other's jokes about how much weight they need to put on to get there.
