I believe that if someone really is comfortable about the way they live, they won't have a problem listening to a stranger telling them otherwise and just forgetting about it in a hearbeat.
Personally I think it would be better for society at large if people spoke up what the thought about the behavior of others more often. It doesn't mean that you have to follow everything you are being told, but it would give you some "precious" hints about what is going on.

My teenage self, deeply unhappy about being so skinny and underdeveloped, thanks you for being considerate enough to tell me that I'm too thin and should eat more.
My husband, who has eczema, also relishes it when well meaning folks enter into conversation with him about how he should avoid dairy produce or not eat oranges or any of the other well meant golden nuggets of unsolicited and worthless advice.
Some of us have to deal with this crap constantly. It's not like being offered a massage when you have a headache or offering someone some zinc/fresh raspberries when they have a cold, or proffering a tissue when a stranger is coughing or sneezing.

I get well meaning emails all the time by people who are deeply concerned about the size of my penis and who want to help me enlarge it. But, hey! I'm very happy with the size of mine so there's no reason whatsoever that I should develop a complex about it.
