The only problem she is in an open office and there are many people around.
I don't want to feel like an idiot if it blow up in my face.
Easier said than done. Maybe I must go over to the Dark Side. All or nothing.
For the love of everything that is unholy and filthy...please do not, under any circumstance approach her.
She has made it abundantly clear that she is not interested.
However, for the sake of entertainment, follow the following steps and post the follow up thread as soon as you can.
Step 1: Send pictures of your cock via email.
Step 2: Follow step 1 with leaving some fecal matter on her chair with a love not from you.
Step 3: Follow step 2 with ejaculating on a tissue and hand it to her saying:"You are so beautiful, you make my cock cry."
The last and final step will be you declaring your love in public, the more people, the better.
When laughter ensues, take up the courage and sing her a ballad, something creepy and emo-ish and cut yourself until she says yes, or until you bleed to death, whichever comes first.
