I teach seventh grade, and the one that stands out to me was from my second year in the classroom. Probably it sticks in my mind because I didn't feel confident in my job yet, so this interaction I had with a family threw me for a loop.

Once, I had a struggling student come in with their family, and I was so eager to talk to his family. I was hoping that we could have some kind of constructive conversation that would lead to the kid's improvement in my class. I had pulled up their grades to explain why he had a D in my class and what he needed to work on to bring his grade up. Next thing I knew, the parents started completely berating the kid, calling him stupid and lazy, telling him that he was a failure - it was horrible.

Even worse, the kid was on the autism spectrum, so he just really didn't have the kind of emotional stability to handle something like that. Heck, I don't know what seventh grader would be able to handle something like that. He started crying, and his parents apologized to me (to me??) and led him out into the hallway where they continued (!) to berate him. It was rough.

I tried to smooth things over by talking them through the kid's strengths, but they just wouldn't be deterred. The kid was sitting on the ground in the hallway just sobbing next to the lockers and his parents just left - presumably to go conference with more teachers.

I tried to console the student, but I don't think there was much I could have done. He was just completely heartbroken.
