Once I read story.A boy's mother died in a car accident. the Dad told him that her mother was in the heaven .So the boy call 110 to asked where is heaven.The police told him that you can buy some red bolluns and attach some card to them,in tha can you can write your word to your mother.The boy did so and continued writong everyday.sometimes his "mother"also written to him and sent some toys to him. In fact ,his "mother"'s letters were written by the police.But the boy went through a good childhood.Maybe "love"is a kindness lie.It give us energetic to let me live happily.严娜
