I have worked with a lot of teenagers . . . many from Catholic High Schools in my area. I don't know how many times, regarding confirmation, I have heard a kid say "Eh, it's all crap. I'm just doing this to keep my parents happy." They went through the motions, made the profession of faith, and as soon as they were out of their parents house, stopped going to church.
