Ever been on a date and you don't like her? And you don't want her to call anymore?
Just talk about electronics... :P It can be amazingly effective!
Say to her: "Guess what.. I simulated a line impedance stabilization network to study differential and common mode noise from a model of a switching power supply. It's difficult to model how all the components capacitively couple to an earth grounded enclosure. For example, unshielded toroidal inductors can capacitively couple to the enclosure......"
She's not gonna call again after that. :P Works every time for me...
Cruel? :P
