I'm a single guy and I can't tell you the amount of times I've been in a bar or a club and talking to some girl, it's all going well and then she asks the dreaded question... so what do you do? What do you say? Tell her the truth? "I am an accoutant"... BOOM, conversation over!! Maybe not straight away but you've struck the mortal blow... believe me, I've tried.
Or do you try and be half honest and say something lame like "I work in finance", or the sexier version "I work in commercial finance", hoping that she's getting images of some slick Christian Bale type investment banker (minus the blood) in her head instead of a tight ass bean counter!
