I have heart that some places children are dismissed first if they have been the most reverent child/children.
In the handbook it says that there ought not to be such a thing as reverence competitions.
This is a thought: how about to just dismiss children class after class!!!
All things is done in order (D&C 88).

Liz Osborn,Longmont, Colorado once said, and I agree):
Sometimes, children respond well to the idea that they get to do things 'just like grown-ups do'. Conversely... can you imagine a temple president telling the folks in the temple chapel he'll pick the reverentest ones to go first...

Just a thought I would like to share.....
