Today when I ask Bob(the man who lives upstairs) about the speaking practice, he is very kind and invited me to his apartment, I saw his lovely son and daughter, they are very cute. So we decided to talk about the children, he likes children very much, he felt very happy when he play with his children, he thinks they like the angel, when he saw them, he will forget something unhappy because he do not want his children have the feeling of  unhappy, he hopes them can keep happying. I agree with him, but I felt a little confusing about some couples do not want to give birth to a baby. He said that some of these couples are also like children, but both of them are busy and do not want to give up their jobs, so they have no baby. However, some couples are dislike children, because sometimes the kids are noisy,   they always keep crying, and another side is they do not want to break their life that just two members in their family, and they can have no worry when they do not love each other. He thinks the kids are very important in a family, sometimes they can keep the family harmonious. In my family, I have a brother, we can always make my parents laugh, and we can also talk with them when they are arguing. So we think the kids are important for a family.
