the scenario of kids running up and down the Aisles looking for Mum & Dad when the plane hits turbulence and the kids get freaked out. Personally it does come down to the parents yet again and them teaching their kids what is acceptable behavior on a plane and whats not and as for babies a shot of brandy/whiskey in warm milk usually does the trick.
If everyone cared and nobody cried
If everyone loved and nobody lied
If everyone shared and swallowed their pride
Then we'd see the day when nobody died....Chad Kroeger
