<human>: Can you provide a brief overview of the text?

A couple of days ago, our English teacher asked us to write an exposition on the topic of "It should be illegal to smack children" for homework. Being the slacker I am, I didn't do it. By the time he called my name, I had written down a few points I could elaborate on. Unfortunately, I am a horrible improviser, so this did not help much. This is how it went:

"Should smacking children be illegal? This is a very versatile question... wait, did I use the word versatile right? Wait, let me start again. Smacking children, umm, shouldn't be illegal because it is too hard to define a smack. For one, there is, like, not much of a difference between patting and, umm, smacking. You could just be giving a congratulatory... is that a word? Anyway, you could just be giving a, uh, tap, and then your child could then, like, sue you."

At this point, some of the guys in my class started imitating me. I then kindly told one of them to shut up. The teacher then said that they *did* have a point, and then decided that I should just go back to my seat because I was doing a horrible job.

I actually really like our teacher. I always feel terrible whenever I turn in my homework late, or am late for class (I am very lazy). My friend suggested I write an exposition to him on why he should forgive me for screwing up in class today. It would show him that I know how to write a good exposition, and that I am truly sorry. My teacher's actually a pretty cool guy, so I could write in a joking fashion. I just need ideas.
<bot>: I didn't do my homework and gave a horrible speech in front of the class. Teacher was not impressed. I am thinking of writing an apology exposition to him, but can't think of anything to write.
