Are you a dutiful person? If you are, then you do as you're told, out of a feeling of duty and obligation. Dutiful children know this means cleaning one's room, taking out the trash, and not talking back!
The adjective dutiful is often used to describe obedient children, servants, and soldiers, as well as anyone else who willingly obeys orders. Not surprisingly, dutiful can also have a somewhat negative meaning. For example, if your graduation speaker gives a painfully boring address, you may respond with "dutiful applause" when it's over. That means you are clapping out of a sense of duty and respect, not because you thought the speech was any good.
