OMG, Don't you just love "Harriet the Spy"? Shhh, don't tell, but I remember (or maybe I dreamed that I remembered) my second grade teacher (that would've been circa 1967) reading that book to us.
I think there was another Harriet the spy book too, for some reason I remember a second book, had the same teacher in 3rd grade, as well. Honest, I wasn't held back....hmmm...maybe I was pushed forward and then....naw....
Anyways, fond memories!
