Discuss the importance of GDP and capital along with the writer's selfishness and ignorance. Also mention the effectiveness of charcoal in filtering dirty water.
your GDP will mean nothing nor will your capital! you are the typical example of a selfish idiot that does not even appreciate a good written letter with some good advice! If your tank is full or probably with your capital your ten tanks are full you probably would rather wash your car than share the water! And by the way you are also bloody ignorant and stupid cause charcoal is one of the best ways to filter dirty water and probably also the safest!
