Winter. Everywhere white pure snow. It makes you want to walk and frolic. Looked through the window and see kids playing outside in the snow, there are a couple of snowmen made. Children slide down the hills, next to them a dog sits and looks at them, his attractive face fun. It seems, too, wanted to play. Winter - a wonderful time.

Зима. Всюду белый чистый снег. Так и хочется гулять и резвиться. Поглядываю через окно и вижу детишек играющих на улице в снежки, стоят уже пару сделанных снеговиков. Дети скатываются с горок, рядом с ними сидит собака и поглядывает на них своей веселой мордашкой. Вроде тоже захотела поиграть. Зима - чудесная пора.

Hello, dear friend!
I am writing to you as agreed. I'm sorry, so long collected his thoughts, there was no time. And news of interest is not so much. I wanted to tell you something unusual, exciting, so writing a letter was postponed and postponed. But as time goes on, and you're probably very expect news from me, I will talk about their daily lives.
At school, things are going well, we can say excellent. If last year there were problems with physics and chemistry, in this I was able to significantly improve their grades. I try to engage yourself more - read, solve puzzles, sometimes watch educational programs and movies. When something does not understand, I ask an older brother to explain and listen carefully. The most interesting thing that I really started to like these things that used to seem boring and difficult. It's great.
Relationship in the classroom remarkable. Teachers often praised us for what we are friendly and give it to others as an example. All school activities we have proved from the best party. Especially memorable New Year's masquerade ball. All our guys have agreed not to buy suits, and sew them yourself, it is so interesting and immediately clear who and how much effort spent on creating attire. It was very unusual and colorful. I send you some pictures, I hope they will be able to convey the atmosphere of the holiday.
