[His smile shifts into something kinder now.]

The best thing you can do, being the best role models you can be for them is proving just how responsible you can be. If the younger children sees this continuously, they'll follow that lead and it would get everyone into trouble. You don't want that, do you?

[The rebellious kids looks somewhat sheepish, apologetic even, and nodded.]
