As with people, it depends on the individual. Some kids are well behaved, positive, and considerate. Some kids are bratty, self centered, and mean. The same can be said for all of us adults. I do think that many of the problems we have with particular kids goes directly back to the parents for not providing a better upbringing. I won't lay all of the faults of children at the feet of their parents, but certain behaviors (like in stores, restaurants, or theaters) can definitely be worked on at home and reinforced in public to ensure a good time is had by all when out in public.
