Every parent has a park or square where their children play after school. I've spent countless hours there because I have two children of very different ages. You make friends and you don't make friends in parks. One day I came across a couple of parents hiding behind some bushes to smoke without their children seeing them. They were supposed to have quit because their children had asked them to, and they didn't want to be found out. I thought about all the surreal things we do for our children and realized there was something there. By the time I got home, I already had a ton of ideas. That's how it all started. The park.
