A good DHV will express alpha qualities but will also leave them with questions about you. For instance say "I was playing a gig somewhere this one time..." BEFORE you say "Oh you're a teacher? That's cool, I'm a guitarist." Let them give you some IoI's so you can judge how well the attraction is going. Also remember that a good DHV has a punchline, that is to say its not always funny, but there should be one sentence at the end of the story that is either a.) the punchline of a funny story or b.) sums up the experience in a well put manner or reveals some learned experience.
From there, either draw from personal experience or lie...I mean, flirt

. I have stories that fall into both categories, but the best ones are always the ones that are true that I exaggerate here or there.
