You always take the train for school every day, and nothing out of usual happened before, until today.

Just as the train approached your stop you felt something in your shoulder, the guy that always sits at your side fell asleep on your shoulder.. he's even snoring a bit.

You didn't even noticed when you missed your stop, just because you were distracted looking at the strange sleeping in your shoulder. He was wearing the uniform from your school, that means he also missed his stop.
