My middle school was predominately white and I was in a couple of classes where the teacher said a lot worse. There was no racist shyt, but the teacher was calling them white kids all types of motherfukkers, a$$holes, shyt heads and stuff.....and yeah he was yelling at the top of his lungs like this white dude. Guys face was all red and spittin and shyt.
I seen a couple of white kids dad's get like this so I just chopped it up to that's how white men act.....
My high schools were different though, although those teachers did care, they were honest about if you didn't want to be there, just leave. You could walk out and go to study hall or iss (in school suspension) until you failed the class and either had to repeat or you dropped out or got expelled.
My pops told me firmly in 5th grade "

don't be acting a fool in class. If I get a letter or a call, that's your ass."
He literally said that and I was
Then like in a sitcom when Carl stops yellin at Eddie then says some heartfelt shyt and they play that sad/loving music he was like
"People are going to mess with you, say things about you or things you don't like. Even the teachers might get on you. Just make sure you're taking care of your business and if you are, at the end of the day can't nobody tell you anything."
He kept his end of the bargain. There was a teacher I really wasnt vibin with but I turned in every assignment on time and was passing the class with like a 97. I bounced a couple times and they ended up calling my pops. He asked me what was going on, I told him how I felt, and showed him my grades. He was upset or disappointed at all. But he did break it down for me how I only had a few more months of that class and never had to see or speak to that teacher again so just continue to do my work and unless shyt really gets bad just take care of my business.
