I wake up at 8 o'clock if I have to go to the university to the first lesson.

If I have to go to the second lesson, I can let myself to sleep a little bit more - untill 10 o'clock.

When I hear the sound of an alarm clock through the dreaming, I open my eyes, watch at the clock, and despite I have to get up and go to the univerity, I decide to continue sleeping further.

In a half of hour, I jump, watch at the clock and understand, what I am terribly late.
