I have two younger brothers. One of them, as a teenager, invented a way to get rid of homework, including a fool. Either I depicted “Oh, I don’t know!” or I did so that I could do the most damage possible (so that they’t be ordered anymore). Parents quickly passed through this and under the motto "What to do, since you are stupid and unadapted to difficult work!" they entrusted him with the most dull and tough work - to drag wood (lived in a private house), to scratch iron pans...

The second brother turned out to be white-handed, looking at all this, quickly made conclusions. Until now (and we are all adults) I have not met people who know how to wash dishes faster and better. What do you know about the method of knot and spinner?
