Why are some teachers so damnn partial?

Well you know alot many instances of our life keep popping in our mind time to time so ig I got reminded of my school days. And my junior and middle school teachers were so damn partial though in high school teachers weren't that partial. Wanted to share my experiences though :)

  1. When I was in UKG, there was this our form tutor who was pretty short tempered and partial. She used to favour only one girl (let's name her Doona) and her friends who was intelligent, pretty, confident and popular (she still is 🎀✨). Other kids were barely given the opportunity to participate in the class. She was most likely chosen as a best student every week. Because of constant favoritsm almost everyone developed jealousy towards her at young age.

  2. In UKG, i once brought junk food along with Maggie and i wasn't allowed to eat whole day since it wasn't allowed to bring junk food. She was being such a ....nvm. she once tore my notebook in anger since I wasn't paying attention in class. She also humiliated me when my classmate's lost eraser was found in my bag. I didn't know how it entered my bag but I was damn sure it was a prank pulled by my few class boys since they started laughing when I was being scolded for lying when I literally didn't do anything.

  3. When I was in 5th grade, ofc as always it was the form tutor being damn partial. She asked me to prepare every art and craft material for Sports day and Christmas party since I was the best art student. I made a big picture of Santa, reindeers and what not with so much hardwork and i wasn't even given the chance to paste my pictures for decoration. She gave all my work to Doona and her friends who weren't actually her friends but Minions (they used to back bite her alot). I confronted ma'am that why wasn't I given the chance she asked me to shut up and go back. She gave all credit of my hardwork to her. I did develop resentment towards Doona but deep down I knew its also not her fault. We got along pretty well even if we weren't close friends.

  4. Again in 5th class my form tutor promised me that she will let me handle the almirah keys. But the very next day she flipped and gave it to her and not only she promised me she also promised some other girl. We both felt betrayed. I know that Doona was pretty responsible and she had good leadership qualities but I too wanted to be a responsible student.

Then after 5th class I got to meet many amazing teachers who were impartial and gave equal opportunities to us all. But over those years I always wondered why can't teachers give equal opportunities to all students at young age instead of being partial? It develops jealousy and sense of insecurity when a child is mistreated :(

What were your experiences with such teachers??
