A little class etiquette that you won't find printed on the syllabus.

This week is so beautiful and just all-around perfect. I don't have crippling amounts of homework, nor do I have any tests. So I feel like I shouldn't spoil it all with a rant...but I will.

Let's see. How should I put this?
For the second Chaucer class period in a row, I have sat in front of someone who has no problem sticking her feet in my butt for a considerable portion of the class time. You know how students will often rest their feet on the metal bars below the chair seat in front of them? Yeah, well this girl completely ignores that handy and socially accepted place to rest her feet. So, she aims higher and sticks her feet on my chair which, in turn, means I get to feel her feet sticking into my tush until either of us moves (and neither of us are willing to budge).

Here are some outside fact which play into this whole scenario.
1) I'm not the only one she has done it to in this class.
2) She has a notable and school-wide reputation for not being the nicest person in the world. This can be noted in that...
3) Isn't it common curtesy not to put your feet on someone's chair so that you aren't invading their butt-space? So, either she's ignorant or rude.
4) I can be pretty stubborn. This is my chair.

Now, with these facts in mind, how do I move on? I have made it obvious that my butt is. right. there. (although maybe a little too timidly). So, there's not really anyway she can't know where her feet are (unless her legs are paralyzed and she can't feel touch or pressure and that is doubtful)! I'm not going to move chairs, because pleeeeeaaaaase honey, you can't win things by being inconsiderate. I'm also not going to slouch so far that I can't feel your feet, because I'm trying not to be a hunchback by the time I'm 35. I'm also not going to passively let you keep your feet there, because it's ridiculously distracting (especially when you wiggle your feet around my tush area). If you like your feet in people's butts so much, maybe I can ram my rear into your feet for you. But, then again, I'm trying not to react like an uncontrolled prick. That, then, also rules out sitting behind her and ramming my feet her rear for a change.

As much as I don't want to face up to this girl, I'm going to have to do it in another way than this passive aggressive way I've dealt with it so far. I really don't want to be a jerk about it, but at the same time, you just can't treat people that way. 

Maybe I should simply just say something to her...
