A childhood belief about teachers

I used to have this teacher with huge jowls, and i had never seen jowls before, so, i naturally assumed that this 'woman' was in fact some kind of 'dog-woman-thing'. The jowls were the saggy cheeks that some dogs have, and plus, she had brown hair, which for some reason made it worse, and a bit of a moustache. I used to think that she would hide in storgage cupords and start turing into a dog. I convinced myself that i had seen a black dog walking thorugh the school halls and that the teacher was always panting.
