I will continue my transition from "former youth worker" to "parent of teenager" in a couple weeks. We gave my fifteen year old son a year of grace (that is, no chaperoning) while he adjusted to being part of a fairly large youth group. Coming up in a couple weeks, however, I will be on the bus and in the housing area (Laguna Beach Christian Retreat Center.)
My son, of course, has the usual fear that I'm going to embarrass him in some way (his fear is probably not without merit...) My usual response to his concern is, "Don't worry, son, I'm sure very soon I'll be asked to lead one of the teen classes on a regular basis."
At any rate, if you're there, seek out the group from the Campus church in Atlanta and ask for the skinny gray-headed guy!
