A co-worker told me recently about a teacher who inspired him. He had visited his teacher once years later, and the teacher pulled one of his essays from a file and gave it to him. My friend was shocked and flattered that his teacher had kept his work for all those years. We spoke of sending our past teachers thank you notes and apologies.

I said, “I did that once. I’m sure I owe a few more teachers.”

My high school geometry teacher was elderly and kind. In retrospect, she was probably ten to fifteen years older than I am at present.

Back in my high school days, I took my socializing seriously for an introvert. I maximized my time in the hallway between classes, chatting with friends making eyes (or something like that) with my boyfriend. I would arrive at the classroom threshold as the bell rang. Mrs. Lee always stood there waiting with a patient smile. If I remember correctly, I asked her if I could go to the restroom almost daily as I arrived almost late. She always let me go. At some point in the school year, she just started taking my books for me, never with an ounce of exasperation. When I returned to class, my books waited for me on my desk.

When Mrs. Lee’s husband passed (He was my elementary school counselor who administered standardized testing and told us to bubble our answers “dark and glossy”), I searched for Mrs. Lee’s address. I found it and mailed my condolences, along with an apology from my former self and a note of appreciation from my adult-teacher self. Now I’m the one who allows restroom breaks when they might not be convenient and even when the students try my patience. I told her that, and you know what? She wrote me back, the kindest note in keeping with my memories of her.

In my twenty-first year of teaching, I still remind myself that kids are kids. We learn character, by witnessing character. I did anyway. Although I made A’s in my geometry class that year, I’ll remember what Mrs. Lee taught me about patience and kindness above all. And I’m grateful.

Do you have a Mrs. Lee? Someone who made a difference that might not even know?
