XXX: The familiar parents. There were two childless couples. Treated and tried. Well, one day, they came to the conclusion that they should try to exchange for a bit of partners. It all worked from the first time. In the process of waiting for children, they divorced and married in reverse. Everything went by mutual agreement, everyone is still communicating.

By the way, the story is told by my mother to me that before people were different. You know, these two families were married in the opposite. There was simply no internet.
