As a parent of a handicapped child who doesn't LOOK handicapped I've fielded quite a few of those. But there are some parenting skills that the roaming public feel compelled to comment on.
For example one such skill that spanned the raising of all three children had to do with my breast feeding techniques. I was always amazed at what people felt compelled to share. I was sitting in a shopping mall and my son was crying. He was hungry. He knew it, I knew it and my breasts knew it (breast feeding moms will know what I mean). I sat down with him, covered myself up and discreetly and we all instantly experienced a Zen moment of peace, quiet and contentment.
Five minutes into the event and older woman (well at least much older than me) came up to me. She was hunched over, trying to get a better look and obviously going to make a comment to me that she felt was called for.
"You aren't breast feeding your child in public?!" she gasped.
Honestly when did this situation become a social gaff. For thousands of years women have been breast feeding their children in all sorts of social situations. However, in the last 100 years or so, it has become "disgusting" and inappropriate to breast feed in public. I refused to sit in a bathroom to feed my child. He had the right to eat anywhere just like any other human being.
I remained calm, looked her straight in the eye and answered, "No. I'm baking a cake." After which I ignored her and let my son ease his hunger and drift off to sleep. She tisked her way down the mall and I had a little chuckle.
