I wonder if perhaps some of the people who get so easily annoyed at children, were the ones who themselves felt like they were an irritation to the adults around them?

I usually find people who claim or act like they hate kids to be childish and selfish and I generally don't like them XD Some are somewhat redeemable if they like other animals enough.

And I have also often wondered how kids are supposed to learn how to learn how to be "decent members of society" when they spend a good time pretty much age-segregated apart from it (school) and are being told to shut up and go away when they're interested in what's going on (and then the adults wonder why they won't be more responsible and pay attention when they've gotten used to being told off and going away to do their own thing XD).
