remove backseat of car....
if her obnoxious friend wants to come too he/she'll have to crawl into the skibox for the ride -> Win-win situation !
+who needs a backseat anyways?
By removing the backseat you're making a bold statement for when you'd hook up with the chick, you're basically saying there's no spot for kids in your life, so in the case you hit it off good, thats one less thing to worry about ....
