I love watching the absolute hush that falls over my students when we premiere a book that our class has written...
I think part of it is the excitement of seeing the page that they made and the joy of seeing those by some of their best friends.
I think another part of it is being able to relive an experience or remember and connect to some learning they have already done.
Whatever reason it is, though, it is absolutely beautiful. Sort of makes me want to do nothing but make books and read them aloud all year long.
