A Childhood Reading Mystery I Thought I'd Solved

One of my clearest and funniest memories from first grade--the 1983-1984 school year for me--is the morning I skipped into class with a book from home in my hands and bragged to my teacher that I'd read it all by myself the night before.  This teacher, Mrs. G, was so sweet and pretty and encouraging--I just loved her--and she oohed and ahhed over my accomplishment and asked me if I'd like to read my book to the class.  Oh, yes!  Pride overcame shyness that morning, I guess, because soon I was sitting in The Teacher Chair with my book with all my classmates fanned out around me as I began to read.  The book had a How-I-Spend-My-Day theme, and its final page showed the narrator settled into bed for the night.  My classmates looked awed by my reading skills--"Wow!  Val can read a whole book!  Just like the teacher!"--and I, who had decided as soon as starting kindergarten the fall before that I wanted to be a teacher when I grew up, was having a ball.  The last sentence of the book was something like, "As I fall asleep at night, I hear the owl" or "Outside my window sits an owl."  Since I hadn't read the book out loud before, I hadn't known until reaching the final word on the final page that I couldn't pronounce "owl."  I stumbled and stuttered and "oh-orrrr-ahhh-owwwwrrrruhhhlllllll"-ed as I tried to shape the letters into a word with my mouth, but no.  My teacher, looking puzzled, came over and gently whispered, "Owl.  Owl," but I still couldn't pronounce that word.  ("Horse" was another word that took me awhile, for whatever reason.)  My classmates didn't laugh and didn't seem any less impressed, and I remember nothing else about the experience except how baffled I was by what had just happened.  If I was already, at six years old, as hard on myself as I would be decades later, I likely focused more on the one missed word than the fact that I'd just gotten to "play Teacher" and read aloud to my entire class.  :)  In any case, I have been trying for ages to figure out what that book had been, and I thought I'd finally found it last week.  The book above looked so promising:  The koala bear character takes us through his/her day, and the final page even ends with an illustration of the bear in (a darling patchwork) bed.  Alas, though!  The story ends without a mention of the owl that tripped me up, and the search continues.  I know, we're all thinking, wouldn't it be funny if this IS the book and I'm just not remembering its final page accurately after all these years, but I really don't think so.  :)  Maybe one of these days, as I hunt down and research 80s trivia like this for the memoir, I'll solve the mystery--and send a copy to sweet Mrs. G, as well.  ♥
