We live in the same earth and some people are happy and other people are sad.We should meet the life in active attitude.My grandma is eighty year-old now and when she was a baby,his parents were dead.She was brought up by her uncle.But one little happy thing makes her satisfied.My brother bought Boilsoft video joiner for mac (one kind of software) and showed it to her.She is so happy too.Even let her eat bread every day and she will be happy too.How lovely my grandma is!
