Input: Text: i'm a high school teacher, and one of my regular duties is as the national honor society coordinator. as part of my job, i handle the club funds, and recently that was a lot of funds, in cash, about $1,200 to be exact. on tuesday, i put the money in the cash box, put the cash box in my cabinet and went home for the night, locking my classroom behind me. when i came back wednesday morning, the money was gone. all of it. even the little sack that held the quarters. students were raising money for a trip to washington d.c. to participate in the closeup program and i lost it. we were in the process of getting a bank account established for our club, but the process had not been completed yet (the club has only been running for about 4 months), so i was in charge of the cash. i locked the classroom, but i didn't lock the fucking cabinet. in fact, i left the keys hanging out of the cabinet. now we have to start raising funds all over again. sadly, this wasn't a student fuck up. this was a big, fat, huge me fuck up, and they are the ones who suffer for it. :(

TIFU and destroyed the hopes and dreams of my students.
