I really think it is the parents shirking their responsibilities as well. Not on HAL, but on CCL once this couple just let their mentally challenged teen roam the ship. He kept walking up to people and bothering them, and even at the lido bar doing the same. Finally on the 5th day, the bartender asked where his parents were. His answer was they are hiding in the room and locked me out.
While I am not a confrontational type person, if I would have seen them after I would have given them an ear full! It was just not annoying to everyone, it was dangerous for the kid.
You always hear.."Kids these days". It should be "Parents these days".
