A teacher burning with rage and a student filled with indignation had this conversation:
Teacher: Where have you been?
Student: Just went out to get my mother to the doctor.
Teacher: Oh! I see. But, no excuses! You're late.
Student: Sorry Sir. I won't repeat that.
Teacher: Come late and say sorry and you're gonna save yourself. Now, your ass will be taking rounds and rounds of the playground until the lights go out.
Could that possibly mean when someone dies or until the night or for quite a long time or when someone is panting or what? I'm confused!
