It's not really at the extreme end of the normal distribution for personality, it's a neurological condition. It's also terrible for raising kids in my experience as because of the large genetic component it's likely one of your kids has it too. So now you have this little firecracker who won't sit still and bugs you near constantly while you just want to retreat into your world and get sucked into what it is that you want to do. You get frustrated and aggravated when they disturb you and they get frustrated and aggravated when you seem disinterested in the thing they're intensely interested in. At least that's how it tends to go in my household.
