That is so true. I am close friends to a family at church, who have the best behaved kids at church (in my opinion, which is slightly baised).

Other kids at church whose parents are not as proactive in disciplining and supervising (and believe, it shows) are nowhere near as good.
Now granted, some kids personalities make them seem better than others, but you
