i am an only child.
[{"role": "system", "content": "An only child is a person with no siblings, either biological or adopted. The term \"only child\" is generally applied only to those individuals who have never had siblings. Some children may have half-siblings or step-siblings, either living at the same house or a different house - especially those who were born considerably later - may have a similar family environment to only children, as may children who have younger siblings from both of the same parents (generally ten or more years). Throughout history, only children were relatively uncommon. From around the middle of the 20th century, birth rates and average family sizes fell sharply, for a number of reasons including increasing costs of raising children and more women having their first child later in life. The proportion of families in the U.S. with only children increased during the Great Depression but fell during the Post\u2013World War II baby boom. After the Korean War ended in 1953, the South Korean government suggested citizens each have one or two children to boost economic prosperity, which resulted in significantly lowered birth rates and a larger number of only children to the country. From 1979 to 2015, the one-child policy in the People's Republic of China restricted most parents to having only one child, although it was subject to local relaxations and individual circumstances (for instance when twins were conceived).\n"}, {"role": "assistant", "content": "I grew up as an only child.
