Question

Помогите перевести на английский."Все страны имеют неписаные, но значимые правила поведения, которые могут быть объяснены только местными. Итак, вы приехали в Россию, но не знаете правил поведения? Я помогу вам выучить основные из них.Во-первых, русские люди обычно уступают места в автобусе пожилым людям. Мы заботимся о наших стариках. Наверняка, это правило должно быть вам знакомо.Во-вторых, русские люди обычно снимают свою обувь перед тем, как войти в дом. Возможно, вам покажется это странным. Но таковы правила поведения в России.В-третьих, обычно мы желаем приятного аппетита перед едой. В вашей стране это не принято, не так ли?Также, при встрече некоторые русские люди целуются.Мы не открываем подарки сразу, после того, как нам их подарили. Есть ещё много других правил.Но мы помним, что иностранцы не знают всех наших правил, и, пока вы дружелюбны и вежливы, не переживайте, что ведёте себя немного странно."

Answer 1

All countries have conventional but important behaviour rules that could be explained by inhabitants only. So, you've come to Russia but you haven't know about these rules yet. I'll help you learn primary of them. 
Firstly,russuians usually cede pleces to aged people in the bus. We take care about our elderly. This rule should be known to you,for sure. 
Secondly,russians usualy take off their footwear before entering the house. Perhaps,it could seems rather strange. But this is russian behaviour rule.
Thirdly, we usualy say "enjoy your meals" to each other before dinner,supper. It's not typical for your country,isn't it? Also,when russians have a meet they can kiss each other. We don't open gifts out of hand,which was presented to us. There are many another rules. But, we have to remember foreigners don't aware about all our rules and as long as you staying friendly and polite don't worry about your a little bit strange behaviour.

Answer 2

All countries have unwritten but significant rules of behavior that can only be explained by locals. So, you've come to Russia but don't know the rules of conduct? I will help you learn the main ones. First of all, Russian people usually give up their seats on the bus to elderly people. We take care of our elderly. Surely, this rule must be familiar to you. Secondly, Russian people usually take off their shoes before entering a house. Perhaps, you may find this strange. But these are the rules of conduct in Russia. Thirdly, we usually wish each other a pleasant meal before eating. In your country, is this not customary, is it? Also, when meeting, some Russian people kiss each other. We do not open gifts immediately after they are given to us. There are many other rules as well. But we remember that foreigners do not know all our rules, and as long as you are friendly and polite, don't worry about behaving a little strangely.
