During a conference, I was pleasantly surprised to be seated next to a very handsome man. We flirted casually through dinner, then grew restless as the dignitaries gave speeches. During one particularly long-winded lecture, my new friend drew a # sign on a cocktail napkin. Elated, I wrote down my phone number.
Looking startled for a moment, he drew another # sign, this time adding an X to the upper-left-hand corner.
