Don't blame the kid. Blame the kids parents or in some cases that they have a disorder just like us. I do not let my kids act out in public. They are expected to behave quietly, respectfully, and appropriately for the setting. That's not being an adult, it's being polite. They are 4 and 2. And they do just fine without any negative affects on their overall wellbeing. Kids are people, just small. The difference is that they are new at it and rely on their parents to teach them...much like you rely on your boss to train you in a new job.
