So I get to school, open my locker and my Biology book is missing.
I didn't have any Biology homework that day so I probably wouldn't have taken it home, and I didn't remember taking it home. The last place I remember it being was on a backpack cubby by my locker.
So throughout the whole day, I SCOUR the school for it. Check with every teacher I can, go to the Lost and Found multiple times, move the cubby WITH ABOUT 200 POUNDS OF BACKPACKS IN IT, and don't find it.
I exit the school building dejected (about 15 minutes after I normally do, making my mom worry and extremely crabby at me for whatever reason) and resign myself to spending a ton of money on a new book.
I get home and it's sitting on my dresser.
MANY FACEPALMS ENSUE
