Write a summary of the text. (In English, approximately 10 lines) Family isn't as easily defined nowadays as it used to be. Although it may seem straightforward, it disregards relatively common family arrangements, that the U.S. Census Bureau's definition that a family is "a group of two or more people who reside together and who are related by birth, marriage, or adoption" has become outdated. All of those who financially contributed to a household were considered family such as that of grandparents who look after their grandchildren or married couples who live in different places. And who is to say that your family is not a family? Throughout time and cultures, families have taken several forms - in ancient Greece, for instance, adults that are not blood-related can also be considered part of a family when they have a close bond to the members of the family, including servants. In many cultures today, there is no one true definition of what a family is. Has there ever been, when you were a kid, a person who you were convinced was part of your family just to later discover they were 'just' your parents' friend? So many changes have gone about in the basic structure of the nuclear family as we knew it, but it is fairly safe to say that the sense of belonging and trust one gets from being part of a family; however it is construed, is fundamental to one's development.
