Cam saves the world

Cam is building with his legos. He is making a train and stacking legos so high on top that it keeps falling over and off the rails. He told me he is filling up the train with food and toys for the people in the big city who don't have any food or toys. He says he has to take lots and lots of food for the people so that's why he is stacking them so high, but every time it falls over, he gets frustrated and annoyed. I suggested his train take two trips so it won't derail and spill all of that food because if the train falls over, he can't deliver the food. Cam looked at me and said "But Mom... they are only legos and I can clean them up."
