Irresponsible Teachers?!

Hey Guys,

Sorry I haven't blogged in a long time. Nothing to actually blog about I suppose.
But here's a situation I came across recently at school, like legit.. yesterday.
My history (shall not be named) homework for section one was put in the grades as MISSING.
Here's the story behind it..
Last Tuesday during TA (homeroom), I went to her room to finish the 10 point section. My friend Amanda finished at the same time as I did (we didn't sit by each-other so NO we did NOT CHEAT. She called us cheaters one time -_-). Anyway, I DID turn it into her. Hand to hand, teacher to student, face to face. Not passed around from student, to student, to student. I missed a BAND LESSON which to you may not be a big deal, but I am a music GEEK! So DUH I need as much help as I possibly can!!
I went to go talk to her after class, she said "You never turned it in", never turned it in... NEVER TURNED IT IN! I was about to go RAGE on her! (With not on.. erm..)
I'm giving her this weekend, if she doesn't find it. I'm going right up to her give her MY story with my details.
Cause I know for a FACT I TURNED IT IN! It makes me so mad! I'm down a grade now because SHE LOST IT! (Which down a grade now was from B+ to a C-) My mom told me to stick to how I feel, so I will defiantly stick to how I feel...
Have you guys ever felt this way? Or has a teacher ever lost a homework of yours?
Comment below, ask me any questions, or anything else to blog about.

Stick with the truth,
Teri♥
