It sounds like a youth group that children are forced to attend.
That, not the ill behavior, is the crux of the matter. One of the reasons my original Lifeteen group I attended did really, really well was because a good number–more than half-- came from families that didn’t care that they were attending a youth group. Kids who WANTED To be there were respectful, engaged and interested. The very few teens who didn’t want to be there eventually came around due to positive peer pressure.
Children who are forced to attend something are going to take their frustration out somewhere.
It might be prudent to find out what makes them tick-what they are excited about–and springboard off of that. Even if it’s the movies…they have to have some interest. Likely, they are quite used to being talked to and not having their concerns heard.
I know parents who would only allow DTS (Dead Theologian Society) and not Lifeteen. It was HARD to get some of those kids out of their shells–because they were accustomed to being talked down to, told what to believe and how to believe it. Many came from families that had a nightly rosary but then they were “lazy” because they asked to pray the Chaplet or the Litany or any number of other church-approved devotions. They were SO shut down. They didn’t believe any adult could care or have their best interest–and their behavior reflected it.
