the green plaid couple

i saw several things today which disturbed me and struck a chord of annoyance.

not that they impacted my day tremendously, but upon observing i was nauseous for a time.

first off:
the green plaid couple
they're in one of my classes-- both wore green plaid. not the same pattern but... still. we're in college, people. that was quirky. what i found unnerving was that he extended his arm across the aisle to grasp her arm awkwardly for nearly the entire 2 hour class period. occasionally she would have to re-situate herself to accommodate the foreign object in her desk space to be able to write.
dude, i know you love her and she's probably in line to be your next mrs., but you can lay off touching her for 2 hours.

next:
nose blowers.
i recognize that cold and flu season is upon us, but please-- if you're going to blow your nose loudly, go out into the hall so my ear drums are not punctured and the professor drown out. if you're the quiet sniffler, just discretely blow your nose rather than timidly sniffling for over an hour. just hearing the amount of snot the nose blower is snuffing out or sniffling back in really really grosses me out.
and most importantly, after you blow your nose, do not look at the contents inside your tissue-- especially when you sit in front of me and i catch a frontal view as well.

the best:
eraser
as i let my eyes wander during class, they settled upon an attractive man. what came next... well, i was not expecting it, and the deed took his attractiveness award down substantially.
sticking the eraser of his mechanical pencil inside his ear, he wiggled it around, removed the pencil, and after a glance, wiped the excess earwax on the desk. 
no. that did not just happen!
but it did.

i plead that individuals refrain from doing repugnant actions, because people like me are innocent bystanders.

please and thank you.
