Of late there are more smart boards and tablets than chalk and blackboards. Only yesterday I saw an iPad on the counter at the butcher where once upon a time there might have been a hand-scrawled specials board. I am heartened by this handwritten blackboard because the very impermanence of the chalk implies that the information changes, reassuring me that the catch is more likely to be a daily one. Today, though, my friends and I are having prawns for lunch.
