For one thing, if a person, if a person has been feeding pets throughout his or her childhood, he or she will be kinder than those who did not feed pets. Take my son as a good example, when he was 3-years-old, my wife and I gave him a litter cute dog as his birthday present. Since then, he changed happier and has not beat other children.是什么意思？
