When you live with an engineer who converts peaches into kilowatt-hours, and your sister-in-law is a doctor, why bring a garden gazebo the size of an average cottage as a souvenir from your vacation? so sometimes you just have to write a book. Yes, the engineer and his sister Iva are back! And with them a lot of novel ideas, innovations and world-class improvers. Because as Iva would say: He who is not lazy grows hops well. This time you will find out about the international relations of chickens in the coop, find out how to age for a casino in Las Vegas, who you can meet on the way to Santiago de Compostela, or how much the lightest waterproof socks weigh. The stories of such a "normal family" written by the author Barbora Černohlávková Večeřová are here for those who want to laugh heartily, or perhaps just learn a lot of bizarre things that they would not even think about.
