People should feel sorry for themselves when they wasting something that they possess.for even though most of us leading a good life nowaday's,but there are still some people spending suffering life.when we enter Mcdonald's and KFC to eating our luxury food,yet they just expecting some food to get rid of their starvation.

　　Like all the parent's said their suferring past day's,we can imagine that 30 year's before they also had spent those day's,witch we can understand from our parent's faces appearances.
