You know, patience is the hardest thing to teach a kid. No matter what you're doing (or, I should say, TRYING to do), they want to interrupt and get you to do what they want you to do for them NOW. Did I mention that they can't wait a few minutes? Did I mention that they seem unable to observe that someone else is busy and to understand that it doesn't matter how many times they say your name (or title), it doesn't change the fact that the adult *STILL* has only two hands?
The thought that "if you do what you've always done, you're going to get what you've always gotten" is surely lost on those with the mentality of a child. That must be the difference between an actual adult and a child.
