100% correct. I have two teens who have been on all 13 cruises with us ( I think they might be upset if we left them home)
They were taught at a very early age to be respectful, courteous and to not disrupt others in their pursuit of fun. By all means have fun and enjoy themselves, but not to the detriment of others. They became familiar at an early age of the phrase, "Lets go have a chat" and the raised right eyebrow and non smiling face that I honed to perfection.

So much more effective than a swat on the butt...but I was prepared to do that too if need be.
I had a friend who permitted her children to run wild in restaraunts (waiters and waitresses dodging kids while balancing platters of food is NOT funny) and after I spoke up to her one day at lunch about her allowing her children (ages 3 and 4 at the time)to run around around and not actually EAT lunch, while my children (same ages) sat at the table, we no longer had lunch together in public places. She told me that since she was paying for her meal and her kids that they could act any way they chose. (Entitled much?) After I disagreed and asked her if she would be paying for my lunch and the lunch of all the other patrons in the place since we were all paying to be there, she called her boys back to the table and we paid our respective bills and left. I think the mindset of what a parent would do at home goes out the window when on vacation. The entitlement kicks in high gear and the supervision and rules go out the verandah door.
