So 2nd year is about a million times easier than the first. Plus, I have the same kids, so I already have a good relationship established with them. This post is nothing more than a funning anecdote in class.
So, I was showing my kids the right way to open a binder, since many of them often use the side ring to do so. I wanted to tell them that when kids do that it is my pet peeve. But first I had to explain what pet peeve meant. So, I start by explain that a pet peeve is a thing that annoys you, often a small thing like when people crack their knuckles or bit their nails. My student, Tim, who is the nicest (albeit lazy) kid, without missing a beat says, “Mr. P, you’re my pet peeve”.
How do you not crack up at that?
