I had Ms. Canavan for my gr. 3 reading teacher. I knew she was young; she lived at home and when we walked home for lunch, she walked home, too! Her parents ran a popular restaurant.
Fast forward to 1998. I was in a week long seminar on authors and Language Arts. I was sitting next to a woman named Cedra in a lecture. I knew it was Ms. Canavan, since I had never met anyone else with that name. So I asked her if she taught at Spaulding School and yes, she was still teaching 3d grade there!
Funny, she must have had her child late in life, because he was only about 6-7 years older than my son. I was eight when I had her, in 1961. She must have been only 21 or 22? She didn't look that old in 1998!
I had so many great teachers, I couldn't list them all here. That's why I became one.
