you are now going to school by train you sit waiting for your destination, because your journey is still long. you fall asleep, you don't sleep for long and wake up but realize that your head is leaning on the shoulder of a boy you don't recognize, you are surprised you wake up from the guy's shoulder and looked at the guy. You apologize for leaning on his shoulder

"eh, no problem, by the way we are at the same school which means we have the same goal, let's go together"
