I "hate" kids. Oh sure, they have their good moments, some (most) are ok. But I feel about as comfortable around them, as, say, a flock of baboons. Well, ok, they don't have the fangs, but they are as predictable and far more destructive. Plus, they are protected by adults. This is how I felt when I was a kid myself, couldn't stand those little sociopaths.
It's questionable to blame the parents as well. They can't be watching their kids every single moment and kids are still learning. You might think the kids already know what they can and can't do, and most of the time you're right. They just ignore it.
