Miro is very funny. Soon after I arrived, he asked me to go outside with him to take a look at something. There were two old Opel Astras in the parking lot. He pointed out that the headlights and the tail lights were exactly alike in both cars. When I started to tell him about the operating principles of combustion engines, he cut me off and changed to subject into what to eat if one gets lost in a forest. He pointed to some tiny mushrooms growing on the lawn in front of one of the Opels and said that eating berries and mushrooms was a good idea to keep oneself fed. I agreed but pointed out that one should not eat unfamiliar mushrooms under any circumstances because of the risk of them being poisonous. I added that not even scientists who study mushrooms know every kind of little brown mushroom of which there are thousands of species. One should never touch any of them.
