I always wonder where you draw the line when, as a parent, you address a teacher--and vice versa.
I've known Little Brother's teacher since he was an infant, and we've been on a first-name basis, which is fine until I'm in the school building, and suddenly, though we are about the same age, I want to call her "Mrs. [insert last name here]." Even when there are no kids around!
The familiarity is fine, I think, when you've known the teacher for a while, when you've volunteered side by side with the person.
But over the past couple of days I have had occasion to email Middle Sister's algebra teacher. I've only met this teacher once--at Back to School Night. He doesn't know me from any of the other parents of his 75 students (or his 75 choir members). He never taught Big Brother. And he's young enough that he could have been one of my students, back when I was teaching.
Yet despite the fact that I addressed my email to him: "Mr. [insert last name here]," he responded back with "Barb."
I did sign my email with my first AND LAST names. Perhaps he didn't feel like typing my whole last name. I'd never in a million years, though, think that it's OK for me to call him by his first name--and I'm at least 10 years his senior.
Really? Is that OK? If you were a teacher, would you do that? I've received emails from several other teachers in the same school in past years, and this is the first time this has happened.
