Once upon a time there was a biology group and an evil head office that decided to cancel the field trip, but the students and teachers would not give up, they had been planning all of those field trips for months.
After weeks of collecting signatures, reunions and many protests from both sides, the evil head office that was only counting on senseless arguments, was defeated, the students were able to go to their field trip without knowing some of the secret reasons of why the teachers fought with them.
They wouldn't let many students go, but they let two extra teachers in, they told us to fight for our field trips because it was our right, but they were using the spots we deserved.
Two of the head teachers turned to the evil side as they made every student pay more than they should for the room, even when they were more in the room to make it cheaper, but three brave students were not going to let that happen and only payed what they were supposed to.
The teachers began looking for the fugitives, checking room by room, counting and registering every student, but the three heroes were smarter and managed to fool them for one more night.
But the next day was not going to bring more luck, as they were getting onto the bus, they cornered them, seat by seat asking for the room information and checking with the hotel, it was the end for them, they were going to get busted.
Sadly that was how one of the evil teachers broke his character, showing his true self in front of everyone, while his partner was trying to figure out what had happened, the other one attacked them for the money, luckily for our heros, the good guy calmed the dragon and helped our heros come out victorious.
At the end some teachers do worry about their students, even when it doesn't show.
