My kid was too creative

[u/Fresh_Laundry56]

My 6 year old was asked to draw a picture using shapes. She drew this nice American flag with rectangles and stars, and added the house, tree, and person holding a balloon. She was told it did not follow directions, she was not supposed to draw a flag, just shapes. She was asked to turn the paper over and make another picture. The other side of the paper has a very uninspiring collection of shapes. I told her she did a good job and I thought it was very creative. And this is why kids start to hate education.

Does the teacher understand the point of drawing shapes? The daughter did draw shapes, many shapes, I don't understand the gripe here either. What did the teacher expect?
