Oliver had been building his new cave for months and was facing a lot of issues doing it all alone. One morning, as he attempted to lift a huge rock, another dinosaur, Max, was passing by and he immediately gave Oliver a hand. Once the rock was set in place, Max offered to help Oliver complete the construction. Happy to have a helping hand with something he was struggling with, he readily accepted. Together the two built the cave in just a few days. Oliver couldn’t thank Max enough and was bidding ‘goodbye’ to him when Max declared, “What are you thanking me for, my friend; we both built this cave together; it is as much mine as it is yours.” Shocked, Oliver regretted his decision of taking Max’s help and realised there was no such thing as a free lunch; there’s always a hidden cost.
