Here’s an example of one of those teachers that just love to see their students squirm in their chairs. Come on, guys! Being a kid is hard enough. The pressure to perform well in school. The unmerciful growing pains of coming into adulthood… This teacher can’t be bothered though.
He loves keeping the kids challenged and on their toes. Their constant complaints and general discontentment fuels his fire and reminds him that he is getting the job done. Perhaps he would have been better suited to be a general in the military?
