Here is a possible dialogue between a teacher and a student discussing missing an assignment submission:
Teacher: Hello, did you submit the assignment that was due yesterday? I didn't see it in the assignment submission folder.
Student: Hi teacher, my apologies. I missed submitting the assignment on time. I had some issues with my internet connection and couldn't submit it before the deadline.
Teacher: I see. Missing deadlines is not okay. This is the second time this has happened. I expect all assignments to be submitted on time.
Student: You're absolutely right, I apologize. I should have submitted it on time or at least sent you a message informing about the delay. I will be more responsible going forward.
Teacher: I accept your apology this time. But I want to see all future assignments submitted on time without any excuses. Consider this a warning. If it happens again, I will have to take further action.
Student: Understood, thank you for the warning. It won't happen again. I will submit all assignments on time from now on.
Teacher: Alright, I'm glad we could have this discussion. Please submit the missed assignment by end of this week. We can then move on from there. Let me know if you have any other issues.
Student: Will do, thanks for your understanding. I appreciate the second chance.
Teacher: You're welcome. Let's get back to work!
