Input: Text: yesterday i was in biology.  it is a good class with an enthusiastic and kind teacher.  he has us do study guides before we get to class so everyone is informed.  it can be a little uptight sometimes because i go to a religious college.  most of the people are not ignorant to sex, drugs, and rock and roll; but the topics are a bit taboo (except rock and roll of course).  

we were discussing the circulatory system in class, specifically the blood.  when the class was asked by the teacher "what are some of the functions of the blood?" students raised their hands to respond "bring oxygen and nutrients to the cells" and "dispose of carbon dioxide and other waste products".

these were, of course, not the only functions of the blood.  when the teacher asked if anyone had any others to add my hand very unfortunately went up.

"to defend the body against invading orgasms"

i immediately realized my mistaking orgasm for organism and flushed as red as the blood we were discussing.  my transformation from a white to a red blood cell sparked some laughter, and a certain girl in the 3rd row spoke up.  you might know the type.  she's the girl that tells jokes when she raises her hand.  they are cringe worthy and take up time.  she speaks in a nasally, grating voice that makes you think that her next words should be "*i'm watching you wazowski, always watching*".

  anyway, she turned around to look at me.  "i'll remember that next time i'm being raped i should just bleed on him a bit and that should do the trick".

the room filled with a mix of disgusted groans and uncontrollable chortles.  i slouched back in my chair making myself small.  anger mixed with my embarrassment, turning my face a deeper red.  i wish i had left class then, but i stayed and endured the uncomfortable awkwardness that followed.  it wasn't fair!  the girl's comment was much much more inappropriate, but i was now associated with it.  i thought that it would pass, but today when word had reached my roommate about the incident i knew that tifu.
