So there is a young couple at my church with 3 children about 5, almost 4 and not quite 3. They are the BEST behaved children I have EVER seen in church. When their parents are greeters, they stand in a line and shake hands, too. During service, they sit in their pew quietly looking at some bible story based books and the older one even follows along with the service (she's just learning how to read).

My question is, my husband and I do not know this couple well (only by sight, not by name). Would it be inapproprate for me/us to ask them what they did so right to raise these incredibly well behaved children? If my child is half as good during church I think I would be happy!
