More and more youth and young adults tend to take a more lax attitude to faith and are less connected to traditional, more mainstream religions.
Passing on our faith to our children and doing so through sacraments is no guarantee that they will not drift away for a time, or even for good. Listening to these stories may help us at least understand the cultural context and world that they see. It may give us better language to reach them and let them know they will always be welcome in Church--and more importantly to be clear on what the Church offers them.
