Less freedom for some means less freedom for everybody, as was so eloquently revealed by Martin Luther King Jr. I thought we would never get a holiday named for him with all the hoopla STILL surrounding the issue of freedom for African Americans. What don't people get about that in relation to children, their OWN children even? They might think there is great virtue in denial. Denial of children and maybe especially there's great virtue in self-denial. I guess it's all just a paradigm shift away.
There is more on saying "yes" at the link below. This doesn't mean people should never advise children or point out problems or say "Sorry, we can't." What it's about is about not *arbitrarily* saying no, but saving it for when the answer really can't be yes.
Some people say "no" before they even think, and then they justify it by all kinds of child-belittling means. You don't have to be one of those people.
