dear david,

how are you? sorry, i couldn't write earlier, as i had a lot to do.

well, i think that russian teenagers are just like every other teenagers. we just do the normal stuff, like watching a movie or meet our friends and go to some sort of restaurant or to mc donalds and eat there. we are also a really social country, we like to talk a lot, so a simple walk in the park is not bad either. 

oh, i didn't know you can skate! do you have some other hobbies i don't know about? what about reading? i like to sing. how about you? do you like music and singing?

well i have to end now, as i still got a lot to do. hope to hear from you soon.

yours,
