Today is Sarah’s last day as a 2nd grader. She is happy and sad about this. Happy that vacation is coming, sad that she won’t be at school any more, and that she won’t be in Ms. Cunningham’s class any more. Ms. Cunningham is, as she told me this morning, the best 2nd grade teacher in the world, and I certainly agree. We couldn’t have hoped for a better teacher, and we are hugely grateful. It’s great teachers like this that make kids love learning. And, of course, the principal at Sarah’s school is one in a million, and positively the best principal in the world.
