When my over-bearing niece decided to bring up the baby-dangling issue in front of a house full of people, I simply reminded her of the time she threw her younger sister down the stairs and almost broke her back. That experience was so tramatic for her cause her mother threw her out of the house and she had to beg her mum to take her back. I did it to point out that everybody make mistakes but we don't have the luxary of fame to keep reminding the world of it. Of course I hit a raw nerve with that story cause both her mother and her sister were present. I never heard another word about Michael for the rest of the evening.
That is what I do. I hit them back with their own misdemeaners, to show them why they should stop judging others, It works all the time.
When they talk about bed-sharing, I simply tell them that most of the world share bed with children. I did too. For plastic surgery, I either tell them that it was common practce among ancient cutures around the world, or I tell them, it is his body to do what he likes.
One of my favourite pass-time is to look at peoples noses in the streets,try it sometime, then You will want to know why the media focus on MJ's nose. I see some of the ugliest noses in the streets every day.
