It was nice to get your message! I'm sorry to hear you were late for classes and got punished, especially since it wasn't your fault. That sounds really frustrating.
To answer your questions, yes, some students in my class do sometimes come late to school. Usually, the reasons are things like oversleeping, missing the bus, or getting stuck in traffic. For minor lateness, the punishment is usually a warning or a note sent home. For repeated lateness, students might get detention or have to attend a meeting with their parents. It depends on how often it happens and the school's policy.
I hope things get better for you and you don't get into trouble for being late again!
Best regards,
