I finally caught it. After having the two Mass Kits for years I was finally able to "catch" them playing Mass. I love how they completely rearrange the room to create the church. They were so creative and yet so faithful. I could hear this correcting each other to insure only respect for what they were playing. I love that. Sometimes I see so much value in the down time. When the kids are left alone they can come up with the coolest things.
