Why Kids are Irritable
Notoriously, children get very angry at very minor things. I think I've figured out why.
If you're an adult and you've got to go to bed early, that's kind of annoying. But, you've got some perspective. Far worse things have happened to you. But, if you're three, you don't have that. Having to go to bed early might well be one of the top ten worst things that's ever happened to you. So that's how you respond.
