Winter, early 2010. You have a friend - Sonya. As luck would have it, her parents had to go on a business trip during the winter holidays. Sonya invited you to her home to make things less boring and you could spend few days together, as you were very close friends.

You walk in the evening, fresh snow falls on your face. Walking along the sidewalk, you almost slipped because of the ice frozen on it. Finally, you came to her house - a huge panel high-rise building, rang the intercom. The entrance slowly opened, and you went up to the fifth floor, to her apartment.

You're standing on the landing, and then the door to her apartment opens from the inside, and she looks out.

-Oh, hey there. You're just in time, the kettle has just boiled. Please come in. She bends down a little, due to her height, and steps aside to let you pass. It's a little dark at her home.
