you're right
but the point is, my english teacher shouldn't act like that, just like the teacher in chapter 6.1
as an adult, if you make a mistake, the mature thing to do is to take accountability, apologize, and correct your action instead of being hostile to the person pointing it out, and to a kid nonetheless

i once had an english teacher in 3rd grade who pronounced 'day' as 'dee'
little me, listening to too much maroon 5, said to him "teacher, isn't it sun-DAY and not sun-DEE?"
he gave me zero for my homework that week and told the principal, who then told my parents, that i was an insolent brat
fun times
