I HATE MY SCIENCE TEACHERRRRRRR

MY SCIENCE TEACHER IS LITERALLY SO STRICT FOR NO REASON. I was late a few times and my citizenship went ALL THE WAY DOWN TO AN F. I'M THE MOST BEHAVED STUDENT IN EVERY SINGLE CLASS! HOW DO I HAVE AN F?? SORRY I WAS LATE FOR A COUPLE OF TIMES, I GUESS I SHOULD'VE JUST CONTROLLED TIME TO GO BACK A FEW MINUTES BUT I DIDN'T. THAT'S ALL MY FAULT. Literally, I only have an F (in Citizenship) in her class because I have her for my first period in the morning. My attendance would be perfect if STUPID DAYLIGHT'S SAVINGS DIDN'T EXIST! It's genuinely so infuriating and makes me wonder if she even cares about me as a student. I'M LITERALLY (admittedly sloppily) TRYING IN YOUR CLASSROOM BUT YOU SHOULD BE GRATEFUL THAT I'M EVEN TRYING!
