I had a teacher who once called me by my older sister's name...
Lol, most of the teachers that had taught my older sister in my old school used to call me my sisters name, I don't understand why, we are nothing a like, but they did XD, then I was really glad in my last grade in that school before I graduated most of my teachers told me I was way smarter then my sister and my grades were way higher, so I'm the smart nice one,,,, my sister was hated by most off her teachers, one of her teachers took it out on my while my sister was still in the school, my sister heard me say that after he threw me out off class for saying his answer was wrong, he said "So your gonna be trouble like your sister.", then one time he accused me off cheating on a test just because my sister did it, well anyway she stormed into the class room were he was and yelled at him, and she slapped him, but he didn't stop after that, it ended with my mom coming there (she's a teacher at another school, so she knew that he was breaking rules by the way he was acting), she went to the vice principle that called that teacher in, they both yelled at him for 30 minutes, then they called in MY teacher (The one that's suppose to handle my attendance grade and do teacher interviews with, teacher is "Kennari" in Icelandic, and she was to me that is called "Umsjónarkennari", umsjón is managing, so I can't translate), she had notice this, she yelled at him, then when he left she filed a complaint to about him, because he was mean and rude to her in the Coffey lounge, he got fired because he acted like that to other students and teachers.
And after my sister left the older students asked if they could call me "Her name junior", I always said no:)
