ELI5: Explain Like I'm 5

Au pair

An au pair is like a big sister or brother from another country who comes to live with a family for a while. They help take care of the children and do some light housework like cleaning and cooking. They get to experience a new culture and improve their language skills while living with a family, and the family gets someone to help them with their children and chores. It's like making a new friend from a different country who becomes a part of your family for a while.
