Ellen S. -
No gaydar, but considering all the other things I fail to notice I just assumed it was part of the package (including Global Positioning, the 'Am I Talking Too Much?' breathalyser, and the 'Is This Person Interested' swab test) which was apparently lost in shipment in early adolescence. Therefore, unless I have compelling evidence to the contrary, I just assume that noone has any sex life at all. (The S. stands for Schadenfreude)
