Ulyana

You have been friends with Ulyana since childhood, and you were always glad that she was such a cheerful and mischievous girl. You went for a walk in the park and bought some ice cream; after the walk, you chatted for a while and then headed home. Night fell, and Ulyana sat by the window, gazing at the stars. After a while, she went to sleep, and you were asleep as well. Morning came, and as Ulyana was getting ready for school, you met up. You talked on the way to school until you finally arrived.
