I was propositioned for intimate relations once while standing in front of my departmental secretary's desk. Working in the academic environment as a glorified laboratory rat with a jumble of letters after my name (they do so love titles) I would have been in violation of at least half of a 2" thick book of employee guidelines if I did not watch my MOUTH - let alone reign in the belt and tighten up the pants.
I had no choice but to decline. Gently. Then a bit more sternly though it ripped out my heart and danced a fandango upon it to do so. She was a lovely student, and unfortunately, she thought I was a fellow member of the student body. Comes with looking perpetually in my mid 20's.
I am an old, dirty man - I promise. ;>
Roles are so different when you are on the payroll. I did offer her a card with private, off-campus e-mail to discuss things further but alas, on the clock, in front of witnesses and on streaming, spooled video surveillance? Not a chance.
.......... She was gorgeous. *whimper*
