Dear Steve,

I was very glad to hear from you again. I haven't written for ages because of my school activities.

In your letter you ask me to tell you about my favorite kind of sports. With a pleasure. I like many kinds of sports but best of all I like football. It's the game of my dream. I play for my school football club "Shkolnik". We are good players and we win almost every competitions.
Besides it I'm a football fan and I like to watch every match on TV or in the stadium. And what about you? Tell me about your favorite kind of sports. That's for me today. I have to go.

Best regards to your family.
Write soon.

Andrey

One of the main rules of etiquette in Russia is the respect for the older generation. So, in Russia it is accepted to give place to older people in public transport, to help to cross the road or even help to carry our bags. Long remain a tradition to pass the women forward, to open their doors and help carry heavy bags and things.
Despite the fact that many people think of Russians as people who have no idea about etiquette, this is not the case. If you have the opportunity to visit your Russian friend's house, do it.
When entering a house remember to remove your shoes and put on Slippers. Russians do not wear shoes in house to maintain cleanliness. Russian love to have guests come to visit, you'll see covered with a lot of dishes, the table, the rules of behavior at the table is absolutely identical to the European one. Russia decided not to start eating until until all the guests gathered around the table, the same end of the meal - is not considered polite to leave the table if any of the guests continued to sample the food.
