Not only does it give your kids something to talk about....it gives something for the parent to relate to the kid about. When you talk about your kid's passions, they listen and it's very cool for them to have you interested, so it opens up a new source for communications. That's great when they hit those tween years and start tuning you out. They suddenly start listening again when you're talking about what they're passionate about. If you can collect and build decks / strategies together, before you know it your child might just think you're alright again (s)
