Sometimes we should not take off the burden

A pair of brothers lived in the 80th floor. One day, they came back home from travel but they found the building had powered failure (Diablo iii Gold), although each of them carried a large bag of luggage, but they had no choice, so the elder brother said to the younger brother: "I think we should climb the stairs." So they carried the heavy luggage and began to climb the stairs. When they reached the 20th floor, they were tired, and the elder brother said: "the luggage is too heavy, maybe we can leave it here and when the electricity recovers we can take the elevator to take it." So they put the luggage on the 20th floor and then continued to climb the stairs. It was much easier after they left the luggage. They climbed and laughed, when they reached the 40th floor, they were so tired. At the moment, they started to blame each other and accused each other did not pay attention to the power failure announcement of the building so that they would climb the stairs. They climbed and quarreled, and they got to the 60th floor, when they reached the 60th floor, they were too tired to quarrel. The younger brother said to his elder brother: "we do not quarrel and we should climb to our home." So they climbed in silent, and finally they got to the 80th floor. They came to the door of their home excitedly, but they found that the key was in the bag which was left in the 20th floor.
