I'm sure there are a lot of people out there who are glad to know that many don't mind noise in first and business class cabins. This will make it much easier for some-children, music, loud talking, obnoxious noises, loud games, etc... Please don't complain when you are flying CX from LAX to HKG and have an appointment during the day of your arrival- you're planning to get some sleep on the way over- but can't since someone sits next to you with a toddler or infant that crys and screams all the way during the 15 hour flight. I think if we would ask how would we want to be treated in a similar situation---the question could be answered rather easily. I repeat---this is not about infants- its really about respect and responsibility.
