He has had some issues keeping the slides in sync with the music, and with keeping the right mikes on. One person suggested that I train him a bit, but I declined. There's nothing much to learn here except to be attentive to what's going on.
I just wrote "what's going on," but the whole service is about "who's going on."
I recall one service in which I was running monitors. The singers needed monitors rather badly, because the drums and electric guitars make it impossible to hear yourself, even 20 rows back, let alone on the platform.
All monitors were muted while the minister led us in the introduction to the Lord's Supper, and then while the elements were being handed out the musicians were supposed to sing. The minister said "Let us bow and pray." I did. That's what the moment is about.
The musicians started up, but turned uncertain pretty quickly. After a few moments I figured out what what I'd forgotten and lit them up again.
Maybe the youngster is spacing out. That is easy to do. I've done it myself many times. Or maybe he's "spacing in" to the meaning and the who, and is distracted from the world and the machinery of the service.
The more complicated we make the service, the more workers there must be and the more the workers have to pay attention to the timing instead of the word.
