Sometimes, it's best to not let students know you are listening to their conversations. Then you hear gems like this:
L: Wait, what if you had OCD AND collected Pokemon?
M: L, that doesn't even make sense.
L: Dude, it totally makes sense. Think deeper. Think about what OCD does. Think about what you gotta go in Pokemon...
A: L, really that doesn't make sense.
L: Ok, listen. OCD makes you have, like, everything in order. If you have Pokemon, and OCD, you're gonna wanna catch' em all.
A: I mean OCD wouldn't mean you'd want to catch them all, it would just mean you'd want them in order. Maybe it kind of makes sense.
L: DUDE! There are Pokemon that you do have, and there are also Pokemon that you do not have. Do you wanna catch em' all? Fine, we'll just talk at lunch.
These students are all in eighth grade.
