Your third parent. Although they boast a degree of education, sadly there are too many that can't even teach, and you wonder what they've been doing for 4-6 years in 'education' college, whatever crappy one it was.

A power hungry pervert who likes to be around children but also likes to be dominant. Usually was picked on as a child.

A person who has been taught that what they are doing is right but is actually wrong. A person who probably did poorly and school and felt they needed to go back. Someone who is normally filled with hatred for people younger then them.

bossy people that take over your mind for at least 6 hours

There are multiple types: good, ok, neutral, bad, and horrendous.
Good type: kids today we will do fun activities to learn the content. 5 questions only from the book.
Ok type: kids do your work and I will not bother you. The work is not fun but it is not much either.
Neutral type: kids I will teach u a lesson and then we will do classwork
Bad type: ANNOYING TEENAGERS JUST DO YOUR WORK AND GTFO OR ELSE DETENTION.
Horrendous type: hey kids. I am a good teacher with a good sense of humor. We do fun activities, so let's start by doing some book work. When we take a test, my bitches and ho's will get higher marks than hardworking people. Also asians will get better grades, as if I score them unfairly as I do with white kids then their parents will come and beat me up. Everyone who is not a favorite or a minority will get B's on tests at best, even if they deserve an A.

The person that makes your life a living hell.

A man or woman that wastes the time of innocent children by teaching them rubbish they can get off Google and if that ain't enough then they unload at least 3 hours load of homework on you to be done by the next day.
