Maybe I'm naive. Or slightly twisted. But when I found out that there was an organisation called Couchsurfing that would allow me to travel the world with my teenagers (for free) while meeting other like-minded people, I jumped at it. Yes, it would mean that we'd be sleeping under the same roof of complete strangers, maybe even on a couch, but we'd get to know interesting people and listen to stories that I hadn't heard a thousand times before. And who knows? They might even invite my teenagers to stay for a few years.
