There is probably little time to make it to Amelia's first hour, as shown by the moon clock up above you. If you're going to get to Amelia, you shouldn't waste time trying to make it somewhere impossibly fast, even if it is closer. Home Ec, Amelia's second class, was indeed farther away from you then her first. However, you'd be cutting it too close trying to make her first class, and you aren't exactly in the best state to fuck around with. You have to get after it and get to her as soon as possible, and thus you do.
The journey starts off pretty easy, the bell doesn't ring until you make it to the center of your school, the lunch room. It is a big circular room that has hallways branching off and an auditorium up between the gym and itself, leading to a stage poking out into the gym. You sprint to the other side of the cafeteria though, making it to the oposite wall the houses doors leading to the auditorium. You don't especially feel like going to there, or cutting through it to go to the gym, so you instead walk along the wall.
Eventually the bell does sound, and giants and giantesses alike rush around you on the way to their classes, but none come near you. Unless the were dragging themselves along the wall, they'd have no need too. You make a note of this handy way of travel for later, before finally making it to the far side of the room. Here was a huge hole leading to another hallway, and you turn and start to go down it. The first door on the left is Amelia's Home Ec classroom, and you are probably only ten minutes late to it. Can they blame you though? You didn't even have time to go to your locker! You chuckle at your own joke as you continue on.
At last, you are here. Outside the Home Ec room, your target awaiting you inside. You let loose a sigh of relief, you made it here alive. Now comes the hard part - getting to Amelia and having her not kill you. Also making sure none of her classmates maim you either. That'd be pretty bad. You slip through a crack in the door and go inside.
The first thing that greets you is the sound of beaters beating. The smell of cooking is filling the room with it's aroama, and you observe that today the class is baking cookies for the end of the year assembly. It's basically an excuse for the teacher's to not draw up lesson plans for the students on one of the last days of school by hosting an event for the whole day in which everyone relaxes and enjoys life. Some can clean out their lockers, others just visit their friends before they're gone for the summer, it's all a very fun event. The whole school attends it, so you'd hate to still be lost and small then. On that note, you make your way towards them all.
Gah! This is hard. Everyone is wearing hairnets and aprons, from the back, they all look pretty much identical. They're too far above for you to easily identify their faces from this far away. You're either going to have to get higher, or get closer. Both of those sound pretty bad, but one has to happen. What do you do?
