Trauma like having a bunch of idiots yammering away in class so that the rest of us can't get an education?

After some Googling on the term "Adverse Childhood Experiences", I found this list: Physical abuse, Sexual abuse, Emotional abuse, Physical neglect, Emotional neglect, Mother treated violently, Substance misuse within household, Household mental illness, Parental separation or divorce, Incarcerated household member.

Still can't find much about how humiliating it is to be punished for disrupting class, though.

It's right there in your list: Emotional Abuse.
