Teacher: "Where is your binder!? YOU AREN'T ALLOWED WITHOUT IT YOU KNOW THAT!
Student: "I TOLD YOU I DON'T FUCKING HAVE ONE!"
Teacher: " WHY NOT!?"
Student: "BECAUSE I HAVE SHITTY PARENTS AND THEY DON'T LOVE ME!!!"
Now this was very tongue-in-cheek, but there is something in there that is honest. I will be the first one to admit I have lost my cool when kids don't have pencils, paper, folders, etc. I think back to my time in school and remember also losing my pencils and pens. You will hear teachers complaining about our students prioritizing clothes, shoes, and hot cheetos over school supplies. Would you have made the same choice as a kid? I may have. School and education are taught and learned, not innate. We are taught what is important either through experience or instruction. Some of our students just plain don't have the same upbringing that prioritizes the things that we do. That is ok. There is nothing wrong with them, but it is our job as educators to positively reinforce behavior that is beneficial rather than flipping out on them. That said, flip our when you need to, but understand that it is not the end of the world and you are probably overreacting.
