I don't even know what i'm doing

I'm Katie and I'm 20 (AAAAAHHHH!!!!) years old. I don't know what else to say other than that...

How roll call will go in the future:

Teacher: Welcome to class students! Please say "here" when I call your name
Teacher: Albus
Albus: Here!
Teacher: Doctor
Doctor: Oh, yes, uhm, hello. I can't talk at the moment, time's gone wibbly. Probably leave a message at the tone or something
Teacher: Uhm... okay? Hermione
Hermione: Yes, I'm here! And when's our first test? I've been studying all summer and-
Red-headed boy in class: Oh my god, Hermione, shut up!
Teacher: And you must be Ron! Okay then. Primrose
Primrose: Here
Random girl in the back of the class: I VOLUNTEER!!
Teacher: And I see Katniss has made it today, as well. Welcome.
Blonde boy: Katniss is here?! Yes!! Here, Katniss, try this bread I baked this morning!!
Brunette boy: Oh you'd better keep your hands off her! She's my best friend! We go hunting together!
Teacher: Peeta! Gale! Stop fighting over Katniss and sit down!
Teacher: Rory
Doctor: Oh, Rory died yesterday, ma'am. But he should be back again tomorrow.
Teacher: ....oh...kay? And lastly, Draco.
Draco: I'm LAST?! My father will hear about this!
