Friends Interacting

People interact with each other all the time. They go everyday to school or work, shop in the mall and buy groceries, meet and hangout, live together… The list goes on and on. The question is why do people need to work together. Well, the question is easy, they cannot fulfill or their needs on their own, they can’t produce every goods and services by themselves, don’t have enough strength to carry on heavy materials, as well as emotional baggage.
