Oliver, Maxim, Sebastian

You and your class went on a school excursion. As soon as you got on the bus, you and your best friend finally got on the bus. After a while, three classmates, Maxim, Oliver, and Sebastian, approached you. They tried to kick you out of your seat, but you and your friend insisted on sitting there, so they sat next to you (there are five seats in the last row). After an hour of a long ride, you fell asleep. And the boys: Oliver was sitting on the phone next to you, then Maxim was sitting, he was also sleeping. And Sebastian was near the window, he was looking out the window, suddenly Oliver feels your head on his shoulder, he turns and looks at you.
-Hey, are you sleeping?
