That one guy who when you hear his name being called during role, you immediately turn your head. Not because he's your best friend or super attractive, but because you remember reading his name all over the Class of _ _ _ _ Facebook group. You already think you know him just based on all his posts and comments. He may have even tried to add you on Facebook... before school even started but you politely ignored his friend request because you haven't even met him and his face isn't worth stalking through the internet and it's not even awkward because he probably doesn't even recognize that you were one of the 2,000 people he added over the summer.
The guy from Last Friday Night. Maybe you did or didn't realize he was in one of your classes when it happened but now you have to sit in the same room as him for the next 2 months and every time he walks in you try not to make eye contact and hope he doesn't remember because you sure remember how bad of a kisser he was and how he always tries to talk to you at parties, but then in class you wish he didn't know you existed to save you both from some embarassment.
The hottie. The only reason you are somewhat excited to wake up and go to your 8am class and maybe, just maybe put on some makeup and non-hoboish clothing. You don't know much about him besides the fact that the back of his head is beautiful and one time he turned around to ask you what the date was, or what answer you got for #5.
The one girl who is in all of your classes so therefore she thinks you are destined to be best friends. You just happen to be taking all of the same divisional requirements but somehow she thinks that you have so much in common and that you should walk to every class together and sit next to each other but you try to make an excuse like, sorry I have to pee before class, don't wait up for me...but sometimes she does and since you are walking in the same direction you can't really avoid her. Also sometimes you are just cranky and tired and don't want to talk to anyone in the morning or maybe you actually care about what you are learning in class but she won't shut up.
