Of course, you're not being rude on purpose. Lamps, seeds on the courts, and rudeness are not your thing. But when you switch to English, the triple lamps fall on your pants. And all because politeness in Ukrainian and politeness in English are very different. If you speak English the way you would speak your native language, it will sound quite rude. But how should you do it?

You need to know that please in a request is impolite. That if you don't know the answer to a question, you can't say I don't know. And that adjectives with a negative connotation should be rephrased. And a few other similar nuances.

You will understand all this in one short course. Learn English not to speak, but to communicate.
