I notice a lot how mean parents can be to their kids, how quick they are to raise their voice when they haven't really done anything wrong. Often times it's a situation that the parents created. It's also usually women... I've noticed that men tend to be a lot more lenient with their kids and play into their childlike wonder. Sometimes they go a bit too far with it but I'd rather tell a kid to stop throwing a ball around the store than see a kid getting yelled at for asking her mom a question over and over again with no response.
It might seem like something small on the surface, but I think it goes a long way.
