Perpetually Tired Boy and Real Life Bobblehead Girl

No, I am not starting up a new comic book with the characters Perpetually Tired Boy and Real Life Bobblehead Girl as the characters. These are two fictional students in two different fictional classes that I made up in my mind who I imagine would keep my occupied during boring classes. I'll begin with Perpetually Tired Boy (PTB from here on). (Keep in mind all the "fictionals" and the conditional text I already wrote as I switch to a different tense, as if if these students really existed, which of course, they do not) In the class that PTB and I share, we both sit in the front row. I sit in the second to last chair all the way to the right of the row, and he sits in the very last chair on the left in the row, so we're pretty far from each other, but being that it's a small class, I can still see him. PTB can usually be seen dozing off. I'm talking some seriously hardcore dozing off. Severe head jerks as he falls into a deep slumber that look like they could cause brain damage. The progression from alert to totally asleep is the best to watch though. PTB will begin sitting upright, then a few minutes into the class I'll notice his eyes looking very heavy. Slowly, blinks become longer and soon are becoming full scale eye shuts. Once they make it to the point of completely shut, the head slowly begins to look downward. And as the head falls and PTB falls into a deeper sleep, the movement of the head downward gets faster until it completely crashes as low as it can go...and PTB is out cold. Usually he regains consciousness in a few seconds, but he can't manage to stay awake for much longer before it all happens again. And as this is just about an everyday occurence, he is dubbed Perpetually Tired Boy. Thank you PTB for keeping me occupied during class. Real Life Bobblehead Girl (RLBG from here on) sits two rows in front of me in a reasonably large lecture (approx. 100-200 students), in the front row, and for those of you keeping up, that puts me in the third row. RLBG will often be sitting in the front row, seemingly listening to the professor's lecture or completely zoned out; I'm not always sure as I'm usually directly behind her. But then, a student will raise a point that RLBG approves of and is in love with wholeheartedly. At this point, as the student is often behind RLBG, she turns her around as far as she can as to potentially make eye contact with the student who had made the point she agreed with. Then, RLBG begins nodding her head with approval very harshly. Not a few subtle nods, but seriously about a minute of up and down head nods. So much so that it seems like the brain would be bouncing around and causing a headache, but apparently it doesn't as she looks to give her approval to select students in this fashion almost every class period. It's as if at the instant that a student raises a good point, someone hits her on the head, and she is a real life bobblehead doll, whose head will continue to nod for 30 seconds or so. Thus, she is known as Real Life Bobblehead Girl. These two students are completely ficticious and no attempts to make contact with them for interviews, conversations or demonstrations of their abilities should be made, because they are not real.
