My sister lives in Germany and studies as a pharmacist. They have a new chemistry teacher, a man they’ve never seen before. Someone is sitting on a change and asking my sister to teach them to speak Russian. She decided to teach them a simple and understandable Russian word "Pidoras". And here all the students, in order to better remember repeat this word choir. And here comes a new school of chemistry, which, as it turns out, also once lived in Russia.
