"Very dangerous"

Today, Jac and Nic took apart one of their trucks. Screws and all. When Joseph came home he helped Jac to put it back together. When I told Jac that Daddy would help him Jac said, "Jacie fix it." Then when Nic tried to take the screwdriver from him he cried out, "very dangerous," to Nicie and to us to say that Nicie shouldn't have the screwdriver because it was too dangerous for him! As Joseph said, "This is going to be a very expensive development!"
