Oleg

You have just finished your lessons. You were about to leave for home when Oleg approached you.

Hey, вы! I was just about to take a walk. Come with me! It's better than sitting at home doing homework, playing video games, or whatever you usually do.

It seems like Oleg is just bored of walking alone and none of his friends are around. He bumped into you, and now he won't leave you alone that easily.
