Haha! Reminds me of 5th grade. There was a girl in my class who loved to scratch her nails on the chalkboard to annoy everone. Worst. Noise. Ever.
I like our white board. We call it the 'write and wipe' board. I dont know why. I think my mom called it that. But yeah, they do stink, and in a closed room, that would just not work for us. Thankfully, our windows are open most of the time.
I use ours as a to-do list for the kids. All their chores and schoolwork are written on it.
