I voted "I am car-free by choice and I am an extrovert." because I don't have a car by choice, and despite looking suitable for a bad-guy role I've been enjoying the BAW 64" trailer which is about the best conversation-piece/ice-breaker on conversation I've ever owned. Every time I'm buying groceries (4 bins and well over 130lbs) or hauling about 50 litres (combination of water jugs and soda and a bag of ice) on a soda/water/ice run, I'm always answering questions and offering solutions. Although I don't put myself out there by hauling a soap box and a PA system, if I was an introvert I'd simply sniffle and excuse myself with a handful of monosyllables. I've even started getting names and shaking hands with anyone I meet twice; patrons at the markets or convience stores, security guards, and people in the neighborhood.
