We all live in this world.We maybe feel unlucky sometimes.But, as you know,in this world there have been a lot of people who can't talk, walk, speak,listen to and see anything.
The invalid need our concerns.If you see an invalid person,you should notjust watch him all the time. You can show your respect to him. Let him feel thegood of the world.
Our government should put benefits into its policy that can make theinvalid happier. The invalid need our help. Please don't grudge your smile .Youcan keep it on you face.
If we concern more of the invaild, our society will become more and morefriendly.Violence will cease.We'll live safely.
