Hey guys,
I thought of a little trick on DHVing in front of a girl without you even opening your mouth while in your car. Implant a "relic" of some sort that represents your job or hobby in the passenger seat of your car. This relic can be a business card of your company, a demo cd of your band, or maybe a new article you've written for a magazine.
Make it easily visible for her to see by sticking it in between seats or placing it on the dashboard. While being the observant creature that she is she will spot it, get curious, and (if some comfort is built) she'll pick it up to examine it while your driving. When she asks questions about it, you can give her your Accomplishment Intro in a non-braggodocious manner.
This give her more of a sense of your identity, without you seeming like your trying to impress her about it. Worked like a charm last night with a cute red-head!
