Kristin,
You've come across the spark that makes seeing glimpses of the Kingdom possible! In actuality church and worship is all about pretending the Kingdom. Just as little children playing house learn about life, we "play" Kingdom to learn about the Life we are called to. ("Beyond Maintenance to Mission," Craig Nessan)  But as adults we take things so seriously. Your friend Brian was given the gift of recognizing we are also called to play with Jesus! I still get comfort from this blog I wrote quite a while ago, <a href="http://davesfaithblog.blogspot.com/2008/04/laughter-as-prayer.html" rel="nofollow">Laughter as Prayer</a>. Enjoy, and go play!
