Whoa!!
I’d say some teachers choose that profession because they hate, abhor, despise children. They know what it means be be one, having been one themselves. So they seek total revenge, vengeance upon childhood. They choose that venue, sadistically, to be able to attack, assault, assail, strike, plunder at the most opportune moment, circumstance. They are so full of malevolence, malice, spitefulness.
I’m a teacher (oh really), that’s how I know!
