One story

A long time ago, there were three people who were going to visit relatives in the distance. The journey was at least two days. The three of them, all the things they needed to bring, were ready to go. There are a total of three burdens, they just one person to take a bag, the first two took the two minimum baggage, the last one took the biggest baggage.

Departing, in the past two days, the burden of the person who took the most burdens was getting lighter and lighter, and the burdens of the two people who had the least burdens were getting heavier and heavier. Want to know why? Because the person who took the most burdens, the breads are all eaten, used, eat less and eat less, use, throw away when used up; those who take the least burden, the baggage They are all clothes. On the way, the clothes they wear are dirty, wet, and put into the bag, which is naturally heavier.
