When my little sister was 2 or 3 years old she had this picture of a cat that she was supposed to color at school. She colored the cat purple. The teacher actually gave her points off because her picture wasn't realistic. I was livid. I was 11 or 12 and I wanted to fight her teacher.
Why was she getting graded assignments? Why was it a coloring page? How TF was a 2 year old supposed to know that purple cats don't exist? Why does that even matter? None of it made sense. To this day, thinking about it makes me angry.
It was my first time realizing that teachers were fallible. Not only that, I was horrified that someone so clearly foolish could have so much power over a youth.
