Three friends convince the fourth that they are all fornicating with their mothers - Ronald goes home to his mother and does what he can to be her lover.
Two brothers farmed potatoes together. One had two daughters and, because Covid prevented them from dating, he felt it was his duty to prepare them to be good wives. His own wife agreed. The other brother had a son and a daughter, and whey they found out what their cousins were doing, they felt like they should participate in getting ready for marriage, too. The result was two families engaged in a taboo lifestyle, which worked as well as the farming did. And the farming worked very well indeed.
