Chalkboards

I grew up in india where we had chalkboards. When I had to teach the first time in uni, I was so bloody nervous that I managed to break every chalk stick in the box. But I still get excited when I hold chalk in my arms. Very primeval reaction. Not usually found these days of whiteboards and board pens. Not fun indeed. 

And then you see this. How extraordinary. The best we would get up to in school was to draw penis pictures. And these Japanese students are something else.
